98-601: Wattle Point Wind Farm is a wind farm near Edithburgh on the Yorke Peninsula in South Australia , which has been operating since April 2005. When it was officially opened in June of that year it was Australia 's largest wind farm at 91 megawatts (122,000 hp ). The installation consists of 55 wind turbines covering 17.5 square kilometres (6.8 sq mi)and was built at a cost of 180 million Australian dollars. It
196-688: A rebound effect in which consumers use the money they save to buy more energy-intensive goods and services. For example, recent technical efficiency improvements in transport and buildings have been largely offset by trends in consumer behaviour , such as selecting larger vehicles and homes. Renewable energy sources are essential to sustainable energy, as they generally strengthen energy security and emit far fewer greenhouse gases than fossil fuels. Renewable energy projects sometimes raise significant sustainability concerns, such as risks to biodiversity when areas of high ecological value are converted to bioenergy production or wind or solar farms. Hydropower
294-445: A capacity of over 6,000 MW by 2012, with a goal of 20,000 MW by 2020. As of December 2020, the 1218 MW Hornsea Wind Farm in the UK is the largest offshore wind farm in the world . Individual wind turbine designs continue to increase in power , resulting in fewer turbines being needed for the same total output. Because they require no fuel, wind farms have less impact on
392-464: A drop in tourism. Some critics claim that wind farms have adverse health effects, but most researchers consider these claims to be pseudoscience (see wind turbine syndrome ). Wind farms can interfere with radar, although in most cases, according to the US Department of Energy, "siting and other mitigations have resolved conflicts and allowed wind projects to co-exist effectively with radar". Location
490-437: A given unit of energy produced, the life-cycle greenhouse-gas emissions of natural gas are around 40 times the emissions of wind or nuclear energy but are much less than coal. Burning natural gas produces around half the emissions of coal when used to generate electricity and around two-thirds the emissions of coal when used to produce heat. Natural gas combustion also produces less air pollution than coal. However, natural gas

The 15 on-shore turbines are spaced 326 metres (1,070 ft) apart, each 70 metres (230 ft) high, with 41 metres (135 ft) long blades, with a rotor diameter of 82 metres (269 ft) and a wind swept area of 5,281 square metres (56,840 sq ft). Phase II was completed in August 2008, and added 5 more wind turbines with the same capacity, and brought
784-430: A minimum of 3.5 times the turbine's rotor diameter of clear space between each adjacent turbine's respective spatial envelope. Closer spacing is possible depending on the turbine model, the conditions at the site, and how the site will be operated. Airflows slow as they approach an obstacle, known as the 'blockage effect', reducing available wind power by 2% for the turbines in front of other turbines. The capacity of
882-406: A path to net-zero emissions . Developing natural gas infrastructure risks carbon lock-in and stranded assets , where new fossil infrastructure either commits to decades of carbon emissions, or has to be written off before it makes a profit. The greenhouse gas emissions of fossil fuel and biomass power plants can be significantly reduced through carbon capture and storage (CCS). Most studies use
980-428: A quarter of all low-carbon energy , making it the second largest source after hydropower. Nuclear power's lifecycle greenhouse gas emissions—including the mining and processing of uranium —are similar to the emissions from renewable energy sources. Nuclear power uses little land per unit of energy produced, compared to the major renewables. Additionally, Nuclear power does not create local air pollution. Although

Biomass is renewable organic material that comes from plants and animals. It can either be burned to produce heat and electricity or be converted into biofuels such as biodiesel and ethanol, which can be used to power vehicles. The climate impact of bioenergy varies considerably depending on where biomass feedstocks come from and how they are grown. For example, burning wood for energy releases carbon dioxide; those emissions can be significantly offset if

Such wind farms are a group of airborne wind energy systems located close to each other connected to the grid at the same point. Wind farms consisting of diverse wind turbines have been proposed in order to efficiently use wider ranges of wind speeds. Such wind farms are proposed to be projected under two criteria: maximization of
1274-627: A small fraction of the energy in sunlight, producing a given amount of bioenergy requires a large amount of land compared to other renewable energy sources. Second-generation biofuels which are produced from non-food plants or waste reduce competition with food production, but may have other negative effects including trade-offs with conservation areas and local air pollution. Relatively sustainable sources of biomass include algae , waste, and crops grown on soil unsuitable for food production. Carbon capture and storage technology can be used to capture emissions from bioenergy power plants. This process
1372-401: A solar panel to produce as much energy as was used for its production. Less energy is needed if materials are recycled rather than mined. In concentrated solar power , solar rays are concentrated by a field of mirrors, heating a fluid. Electricity is produced from the resulting steam with a heat engine . Concentrated solar power can support dispatchable power generation , as some of the heat

Reliable and affordable energy, particularly electricity, is essential for health care, education, and economic development. As of 2020, 790 million people in developing countries do not have access to electricity, and around 2.6 billion rely on burning polluting fuels for cooking. Improving energy access in
1666-465: A total capacity of 539 MW. An important limiting factor of wind power is variable power generated by wind farms. In most locations the wind blows only part of the time, which means that there has to be back-up capacity of dispatchable generation capacity to cover periods that the wind is not blowing. To address this issue it has been proposed to create a " supergrid " to connect national grids together across western Europe , ranging from Denmark across
1764-640: A tunnel like pass towards areas of lower pressure and flatter land. Passes used for wind farms like the San Gorgonio Pass and Altamont Pass are known for their abundant wind resource capacity and capability for large-scale wind farms. These types of passes were the first places in the 1980s to have heavily invested large-scale wind farms after approval for wind energy development by the U.S. Bureau of Land Management. From these wind farms, developers learned much about turbulence and crowding effects of large-scale wind projects, which were previously unresearched, in
1862-423: A working assumption that CCS can capture 85–90% of the carbon dioxide (CO 2 ) emissions from a power plant. Even if 90% of emitted CO 2 is captured from a coal-fired power plant, its uncaptured emissions are still many times greater than the emissions of nuclear, solar or wind energy per unit of electricity produced. Since coal plants using CCS are less efficient, they require more coal and thus increase
1960-569: Is Earth's primary source of energy, a clean and abundantly available resource in many regions. In 2019, solar power provided around 3% of global electricity, mostly through solar panels based on photovoltaic cells (PV). Solar PV is expected to be the electricity source with the largest installed capacity worldwide by 2027. The panels are mounted on top of buildings or installed in utility-scale solar parks . Costs of solar photovoltaic cells have dropped rapidly, driving strong growth in worldwide capacity. The cost of electricity from new solar farms
2058-803: Is a German wind turbine manufacturer. In the end of 2011 49.6 MW was expected to be completed. The Pakistani government also issued a Letter Of Interest in a 100 MW Wind power plant to FFCEL. The Pakistani government had plans to achieve electric power generation of up to 2500 MW by the end of 2015 from wind energy to bring down an energy shortage. Currently four wind farms are operational (Fauji Fertilizer 49.5 MW (subsidiary of Fauji Foundation), Three Gorges 49.5 MW, Zorlu Energy Pakistan 56 MW, Sapphire Wind Power Company Limited 52.6 MW) and six are under construction phase ( Master Wind Energy Limited 52.6 MW, Sachal Energy Development Limited 49.5 MW, Yunus Energy Limited 49.5 MW, Gul Energy 49.5 MW, Metro Energy 49.5 MW, Tapal Energy) and were expected to achieve COD in 2017.

The technology to curb methane leaks is widely available but it is not always used. Switching from coal to natural gas reduces emissions in the short term and thus contributes to climate change mitigation . However, in the long term it does not provide
2450-472: Is competitive with, or in many places, cheaper than electricity from existing coal plants. Various projections of future energy use identify solar PV as one of the main sources of energy generation in a sustainable mix. Most components of solar panels can be easily recycled, but this is not always done in the absence of regulation. Panels typically contain heavy metals , so they pose environmental risks if put in landfills . It takes fewer than two years for

The location was chosen after identification as having one of mainland Australia's highest average wind speeds. The wind farm was officially opened by South Australian Premier Mike Rann and Southern Hydro Chairman, Dr Keith Turner . The opening was opposed by some of the local Indigenous Australians ,
2646-504: Is controversial. Nuclear power does not produce carbon pollution or air pollution, but has drawbacks that include radioactive waste , the risk of nuclear proliferation , and the risk of accidents . Switching from coal to natural gas has environmental benefits, including a lower climate impact , but may lead to a delay in switching to more sustainable options. Carbon capture and storage can be built into power plants to remove their carbon dioxide (CO 2 ) emissions, but this technology
2744-439: Is controversy over whether nuclear power is sustainable, in part due to concerns around nuclear waste , nuclear weapon proliferation , and accidents . Radioactive nuclear waste must be managed for thousands of years and nuclear power plants create fissile material that can be used for weapons. For each unit of energy produced, nuclear energy has caused far fewer accidental and pollution-related deaths than fossil fuels, and
2842-416: Is critical to the overall success of a wind farm. Additional conditions contributing to a successful wind farm location include: wind conditions, access to electric transmission, physical access, and local electricity prices. The faster the average wind speed, the more electricity the wind turbine will generate, so faster winds are generally economically better for wind farm developments. The balancing factor
2940-408: Is crucial to determining site potential in order to finance the project. Local winds are often monitored for a year or more, detailed wind maps are constructed, along with rigorous grid capability studies conducted, before any wind generators are installed. The wind blows faster at higher altitudes because of the reduced influence of drag. The increase in velocity with altitude is most dramatic near

Around 790 million people in developing countries lack access to electricity , and 2.6 billion rely on polluting fuels such as wood or charcoal to cook. Cooking with biomass plus fossil fuel pollution causes an estimated 7 million deaths each year. Limiting global warming to 2 °C (3.6 °F) will require transforming energy production , distribution, storage, and consumption. Universal access to clean electricity can have major benefits to

ATC is the measure of the remaining capacity in a transmission system available for further integration of two interconnected areas without significant upgrades to existing transmission lines and substations. Significant equipment upgrades have substantial costs, potentially undermining the viability of a project within a location, regardless of wind resource availability. Once
3234-466: Is harvested unsustainably. Bioenergy feedstocks typically require significant amounts of energy to harvest, dry, and transport; the energy usage for these processes may emit greenhouse gases. In some cases, the impacts of land-use change , cultivation, and processing can result in higher overall carbon emissions for bioenergy compared to using fossil fuels. Use of farmland for growing biomass can result in less land being available for growing food . In

However, BECCS can also result in net positive emissions depending on how the biomass material is grown, harvested, and transported. Deployment of BECCS at scales described in some climate change mitigation pathways would require converting large amounts of cropland. Marine energy has
3430-558: Is often cheaper than existing coal plants and competitive with natural gas and nuclear. Wind turbines can also be placed offshore, where winds are steadier and stronger than on land but construction and maintenance costs are higher. Onshore wind farms, often built in wild or rural areas, have a visual impact on the landscape. While collisions with wind turbines kill both bats and to a lesser extent birds, these impacts are lower than from other infrastructure such as windows and transmission lines . The noise and flickering light created by
3528-955: Is ongoing. Hydroelectric plants convert the energy of moving water into electricity. In 2020, hydropower supplied 17% of the world's electricity, down from a high of nearly 20% in the mid-to-late 20th century. In conventional hydropower, a reservoir is created behind a dam. Conventional hydropower plants provide a highly flexible, dispatchable electricity supply. They can be combined with wind and solar power to meet peaks in demand and to compensate when wind and sun are less available. Compared to reservoir-based facilities, run-of-the-river hydroelectricity generally has less environmental impact. However, its ability to generate power depends on river flow, which can vary with daily and seasonal weather. Reservoirs provide water quantity controls that are used for flood control and flexible electricity output while also providing security during drought for drinking water supply and irrigation. Hydropower ranks among

The average power in the wind is not proportional to the average wind speed. For this reason, the ideal wind conditions would be strong but consistent winds with low turbulence coming from a single direction. Mountain passes are ideal locations for wind farms under these conditions. Mountain passes channel wind, blocked by mountains, through

5684-1194: The concept of sustainability applies to energy on a global scale. Working definitions of sustainable energy encompass multiple dimensions of sustainability such as environmental, economic, and social dimensions. Historically, the concept of sustainable energy development has focused on emissions and on energy security . Since the early 1990s, the concept has broadened to encompass wider social and economic issues. The environmental dimension of sustainability includes greenhouse gas emissions , impacts on biodiversity and ecosystems, hazardous waste and toxic emissions, water consumption, and depletion of non-renewable resources. Energy sources with low environmental impact are sometimes called green energy or clean energy . The economic dimension of sustainability covers economic development, efficient use of energy, and energy security to ensure that each country has constant access to sufficient energy. Social issues include access to affordable and reliable energy for all people, workers' rights , and land rights.

7056-445: The most resource and opportunity are eventually developed. After the deadline to request a place in the queue has passed, many firms will withdraw their requests after gauging the competition in order to make back some of the deposit for each request that is determined too risky in comparison to other larger firms' requests. A major factor in wind-farm design is the spacing between the turbines, both laterally and axially (with respect to
7154-485: The pollution associated with mining and transporting coal. CCS is one of the most expensive ways of reducing emissions in the energy sector. Deployment of this technology is very limited. As of 2024, CCS is used in only 5 power plants and in 39 other facilities. Nuclear power has been used since the 1950s as a low-carbon source of baseload electricity. Nuclear power plants in over 30 countries generate about 10% of global electricity. As of 2019, nuclear generated over
7252-409: The prevailing winds). The closer the turbines are together, the more the upwind turbines block wind from their rear neighbors (wake effect). However, spacing turbines far apart increases the costs of roads and power cables, and raises the amount of land needed to install a specific capacity of turbines. As a result of these factors, turbine spacing varies by site. Generally speaking, manufacturers require
7350-514: The proportion of renewable energy in the world's energy supply. According to the International Energy Agency, renewable energy sources like wind and solar power are now a commonplace source of electricity, making up 70% of all new investments made in the world's power generation. The Agency expects renewables to become the primary energy source for electricity generation globally in the next three years, overtaking coal. The Sun
7448-592: The release of toxins into the environment, and water scarcity. As of 2019, 85% of the world's energy needs are met by burning fossil fuels. Energy production and consumption are responsible for 76% of annual human-caused greenhouse gas emissions as of 2018. The 2015 international Paris Agreement on climate change aims to limit global warming to well below 2 °C (3.6 °F) and preferably to 1.5 °C (2.7 °F); achieving this goal will require that emissions be reduced as soon as possible and reach net-zero by mid-century. The burning of fossil fuels and biomass
7546-585: The renewable energy sector. In 2011 the European Union had a total installed wind capacity of 93,957 MW. Germany had the third-largest capacity in the world (after China and the United States), with an installed capacity of 29,060 MW at the end of 2011. Spain had 21,674 MW, and Italy and France each had between 6,000 and 7,000 MW. By January 2014, the UK installed capacity was 10,495 MW. But energy production can be different from capacity – in 2010, Spain had
7644-532: The same goods or services, or delivering comparable services with less goods—is a cornerstone of many sustainable energy strategies. The International Energy Agency (IEA) has estimated that increasing energy efficiency could achieve 40% of greenhouse gas emission reductions needed to fulfil the Paris Agreement's goals. Energy can be conserved by increasing the technical efficiency of appliances, vehicles, industrial processes, and buildings. Another approach
7742-400: The same location used to produce electricity . Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore . Many of the largest operational onshore wind farms are located in China, India, and the United States. For example, the largest wind farm in the world , Gansu Wind Farm in China had
7840-565: The smallest share of the energy market. It includes OTEC , tidal power , which is approaching maturity, and wave power , which is earlier in its development. Two tidal barrage systems in France and in South Korea make up 90% of global production. While single marine energy devices pose little risk to the environment, the impacts of larger devices are less well known. Switching from coal to natural gas has advantages in terms of sustainability. For
7938-571: The southern North Sea to England and the Celtic Sea to Ireland, and further south to France and Spain especially in Higueruela which was for some time the biggest wind farm in the world. The idea is that by the time a low pressure area has moved away from Denmark to the Baltic Sea the next low appears off the coast of Ireland. Therefore, while it is true that the wind is not blowing everywhere all of
8036-410: The surface and is affected by topography, surface roughness, and upwind obstacles such as trees or buildings. At altitudes of thousands of feet/hundreds of metres above sea level, the power in the wind decreases proportional to the decrease in air density. Often in heavily saturated energy markets, the first step in site selection for large-scale wind projects, before wind resource data collection,
8134-418: The surrounding population at risk. Geothermal energy is produced by tapping into deep underground heat and harnessing it to generate electricity or to heat water and buildings. The use of geothermal energy is concentrated in regions where heat extraction is economical: a combination is needed of high temperatures, heat flow, and permeability (the ability of the rock to allow fluids to pass through). Power
8232-677: The time, it will tend to be blowing somewhere. In July 2022, Seagreen , the world's deepest fixed-bottom wind farm, became operative. Located 26 miles off the Angus coastline, in Scotland, it has 114 turbines that generate 1.1 gigawatts (GW) of electricity. India has the fifth largest installed wind power capacity in the world. As of 31 March 2014, the installed capacity of wind power was 21136.3 MW mainly spread across Tamil Nadu state (7253 MW). Wind power accounts nearly 8.5% of India's total installed power generation capacity, and it generates 1.6% of
8330-701: The total capacity to 33 MW. All 20 turbines describes a graceful arc reflecting the shoreline of Bangui Bay. Adjacent municipalities of Burgos and Pagudpud followed with 50 and 27 wind turbines with a capacity of 3 MW each for a Total of 150 MW and 81 MW respectively. Two other wind farms were built outside of Ilocos Norte, the Pililla Wind Farm in Rizal and the Mindoro Wind Farm near Puerto Galera in Oriental Mindoro . Sri Lanka has received funding from
8428-422: The trees that were harvested are replaced by new trees in a well-managed forest, as the new trees will absorb carbon dioxide from the air as they grow. However, the establishment and cultivation of bioenergy crops can displace natural ecosystems , degrade soils , and consume water resources and synthetic fertilisers. Approximately one-third of all wood used for traditional heating and cooking in tropical areas
8526-401: The turbines can cause annoyance and constrain construction near densely populated areas. Wind power, in contrast to nuclear and fossil fuel plants, does not consume water. Little energy is needed for wind turbine construction compared to the energy produced by the wind power plant itself. Turbine blades are not fully recyclable, and research into methods of manufacturing easier-to-recycle blades
8624-607: The wind accelerates over a ridge. The additional wind speeds gained in this way can increase energy produced because more wind goes through the turbines. The exact position of each turbine matters, because a difference of 30 metres could potentially double output. This careful placement is referred to as 'micro-siting'. Europe is the leader in offshore wind energy, with the first offshore wind farm (Vindeby) being installed in Denmark in 1991. As of 2010, there were 39 offshore wind farms in waters off Belgium, Denmark, Finland, Germany, Ireland,
8722-785: The wind blows and the sun shines. Switching to renewable energy can therefore require electrical grid upgrades, such as the addition of energy storage . Some processes that are difficult to electrify can use hydrogen fuel produced from low-emission energy sources. In the International Energy Agency 's proposal for achieving net zero emissions by 2050, about 35% of the reduction in emissions depends on technologies that are still in development as of 2023. Wind and solar market share grew to 8.5% of worldwide electricity in 2019, and costs continue to fall. The Intergovernmental Panel on Climate Change (IPCC) estimates that 2.5% of world gross domestic product (GDP) would need to be invested in
8820-457: The wind turbines. Therefore, special fast service vehicles for installation (like Wind Turbine Shuttle) as well as for maintenance (including heave compensation and heave compensated working platforms to allow the service staff to enter the wind turbine also at difficult weather conditions) are required. So-called inertial and optical based Ship Stabilization and Motion Control systems (iSSMC) are used for that. Experimental wind farms consisting of
8918-535: The world at 659 MW , followed by the London Array (630 MW) also in the UK. Offshore wind turbines are less obtrusive than turbines on land, as their apparent size and noise is mitigated by distance. Because water has less surface roughness than land (especially deeper water), the average wind speed is usually considerably higher over open water. Capacity factors (utilisation rates) are considerably higher than for onshore locations. The province of Ontario, Canada
9016-410: The world in wind energy production, going from 2,599 MW of capacity in 2006 to 62,733 MW at the end of 2011. However, the rapid growth outpaced China's infrastructure and new construction slowed significantly in 2012. At the end of 2009, wind power in China accounted for 25.1 gigawatts (GW) of electricity generating capacity, and China has identified wind power as a key growth component of
9114-463: The world's first wind farm was 0.6 MW, produced by 20 wind turbines rated at 30 kilowatts each, installed on the shoulder of Crotched Mountain in southern New Hampshire in December 1980. Onshore turbine installations in hilly or mountainous regions tend to be on ridges generally three kilometres or more inland from the nearest shoreline. This is done to exploit the topographic acceleration as
9212-603: The world's population lives with levels of air pollution that exceed the World Health Organization recommended limits. Cooking with polluting fuels such as wood, animal dung, coal, or kerosene is responsible for nearly all indoor air pollution, which causes an estimated 1.6 to 3.8 million deaths annually, and also contributes significantly to outdoor air pollution. Health effects are concentrated among women, who are likely to be responsible for cooking, and young children. Environmental impacts extend beyond
9310-746: Was developed by the Belgian company Electrawinds. Sustainable energy Energy is sustainable if it "meets the needs of the present without compromising the ability of future generations to meet their own needs." Definitions of sustainable energy usually look at its effects on the environment, the economy, and society. These impacts range from greenhouse gas emissions and air pollution to energy poverty and toxic waste . Renewable energy sources such as wind , hydro , solar , and geothermal energy can cause environmental damage but are generally far more sustainable than fossil fuel sources. The role of non-renewable energy sources in sustainable energy
9408-399: Was inaugurated in December 2015, and is the first large scale wind farm project in the region. Morocco has undertaken a vast wind energy program, to support the development of renewable energy and energy efficiency in the country. The Moroccan Integrated Wind Energy Project, spanning over a period of 10 years with a total investment estimated at $ 3.25 billion, will enable the country to bring
9506-651: Was owned by Meridian Energy of New Zealand until October 2005, when it was bought by the Australian Gas Light Company (AGL). The windfarm was acquired by Alinta in October 2006, as part of an asset merger with AGL, and subsequently by the ANZ Bank 's Energy Infrastructure Trust, for 225 million dollars on 23 April 2007. The District Council of Yorke Peninsula approved a second wind farm, Wattle Point Stage 2. However it did not proceed due to insufficient capacity in
9604-501: Was the 7th country in the world in terms of installed wind power (21 GW), and the 4th largest producer of wind energy in the world (72 TWh), behind China, USA and Germany. The largest wind farm in the country is the Complexo eólico Lagoa dos Ventos in the State of Piauí , onshore with a current capacity of 1,000 MW being expanded to 1,500 MW. In just five years, China leapfrogged the rest of
