At-a-glance Renewable energy is the fastest-growing energy source in the United States, increasing 42 percent from to up 90 percent from to Renewables made up nearly 20 percent of utility-scale U.
Solar generation including distributed , which made up 3. Globally, renewables made up 29 percent of electricity generation in , much of it from hydropower A record amount of over GW of renewable power capacity was added globally during Renewable ethanol and biodiesel transportation fuels made up more than 17 percent of total U. Renewable Supply and Demand Renewable energy is the fastest-growing energy source globally and in the United States.
Globally: About Renewables made up 29 percent of global electricity generation by the end of Led by wind power and solar PV, more than GW of capacity was added in , an increase of nearly 10 percent in total installed renewable power capacity.
In the United States: Almost 5 percent of the energy consumed across sectors in the United States was from renewable sources in Renewables made up Most of the increase is expected to come from wind and solar.
Non-hydro renewables have increased their share of electric power generation from less than 1 percent in to over Renewable Energy Drivers Factors affecting renewable energy deployment include market conditions e.
Global weighted average levelized cost of electricity from utility-scale power generation technologies, and Policy Drivers Two federal tax credits have encouraged renewable energy in the United States: The production tax credit PTC , first enacted in and subsequently amended, was a corporate tax credit available to a wide range of renewable technologies including wind, landfill gas, geothermal, and small hydroelectric.
For eligible technologies, the utility received a 2. The PTC is currently being phased out; at the end of December , the PTC was extended for another year at 60 percent of the full credit amount, and facilities beginning construction after December 31, will no longer be able to claim this credit. The investment tax credit ITC is earned when qualifying equipment, including solar hot water, photovoltaics, and small wind turbines, are placed into service.
The credit reduces installation costs and shortens the payback time of these technologies. It will phase down to 10 percent in from 26 percent in Types of Renewable Energy Renewable energy comes from sources that can be regenerated or naturally replenished. The main sources are: Water hydropower and hydrokinetic Wind Solar power and hot water Biomass biofuel and biopower Geothermal power and heating All sources of renewable energy are used to generate electric power. Water Large conventional hydropower projects currently provide the majority of renewable electric power generation worldwide.
Other Hydroelectric Power Generation Small hydropower projects, generally less than 10 megawatts MW , and micro-hydropower less than 1 MW are less costly to develop and have a lower environmental impact than large conventional hydropower projects.
Hydroelectric Power Generation. Source Environment Canada, Wind Wind was the second largest renewable energy source worldwide after hydropower for power generation. Source GE, Vox, Solar Solar energy resources are massive and widespread, and they can be harnessed anywhere that receives sunlight. Solar energy can be captured for electricity production using: A solar or photovoltaic cell, which converts sunlight into electricity using the photoelectric effect.
Typically, photovoltaics are found on the roofs of residential and commercial buildings. Additionally, utilities have constructed large greater than MW photovoltaic facilities that require anywhere from 5 to 13 acres per MW , depending on the technologies used. In the United States, non-residential solar e.
Concentrating solar power CSP , which uses lenses or mirrors to concentrate sunlight into a narrow beam that heats a fluid, producing steam to drive a turbine that generates electricity. Concentrating solar power projects are larger-scale than residential or commercial PV and are often owned and operated by electric utilities.
Although utility-scale CSP plants were in operation long before solar photovoltaics became widely commercialized, solar photovoltaics have largely taken over this market, due to their declining costs.
Global CSP capacity grew only 1. Concentrating Solar Power. Notes Solar collectors i. Source U. Biomass Biomass energy sources are used to generate electricity and provide direct heating, and can be converted into biofuels as a direct substitute for fossil fuels used in transportation. Geothermal Geothermal provided an estimated TWh globally in , with 97 TWh in the form of electricity with an estimated Geothermal Power Station.
Source BBC Science. Renewable Energy Indicators, Wind resources are abundant in the Great Plains, Iowa, Minnesota, along the spine of Appalachian Mountains, in the Western Mountains, and many off-shore locations. Solar photovoltaic and concentrating solar power resources are the highest in the desert Southwest and diminish in intensity in a northward direction. The best biomass resources are in the upper central plains corn and forests of the Pacific Northwest. Traditional geothermal resources are concentrated in the Western United States.
Photovoltaic Solar Resources. Geothermal Resource. Find out more by visiting our marine energy page. Although it harnesses a power directly below our feet, geothermal energy is of negligible importance in the UK compared to countries such as Iceland, where geothermal heat is much more freely available. This is the conversion of solid fuel made from plant materials into electricity.
Although fundamentally, biomass involves burning organic materials to produce electricity, and nowadays this is a much cleaner, more energy-efficient process. By converting agricultural, industrial and domestic waste into solid, liquid and gas fuel, biomass generates power at a much lower economic and environmental cost.
Fossil fuels are not a renewable source of energy because they are not infinite. Plus, they release carbon dioxide into our atmosphere which contributes to climate change and global warming. On the one hand, wood is a renewable resource — provided it comes from sustainably managed forests.
Compressed biomass fuels produce more energy than logs too. On the other hand, burning wood whether it be raw timber or processed waste releases particles into our atmosphere. As world population rises, so does the demand for energy in order to power our homes, businesses and communities.
Innovation and expansion of renewable sources of energy is key to maintaining a sustainable level of energy and protect our planet from climate change.
In , the UK hit a new amazing renewable energy milestone. On Wednesday 10th June, the country celebrated two months of running purely on renewable energy for the first time ever. This is a great step in the right direction for renewables. This will drive down the price of renewables — great for the planet, and great for our wallets. EDF Renewables.
