Green industrial policy
Green industrial policy (GIP) is strategic government policy that attempts to accelerate the development and growth of green industries to transition towards a low-carbon economy. Green industrial policy is necessary because green industries such as renewable energy and low-carbon public transportation infrastructure…
Environmental policy of the first Trump administration
The environmental policy of the first Donald Trump administration represented a shift from the policy priorities and goals of the preceding Barack Obama administration. Where President Obama's environmental agenda prioritized the reduction of carbon emissions through the use of renewable energy with the goal of…
Net metering in the United States
Net metering is a policy by many states in the United States designed to help the adoption of renewable energy. Net metering was pioneered in the United States as a way to allow solar and wind to provide electricity whenever available and allow use of that electricity whenever it was needed, beginning with utilities…
Power purchase agreement
A power purchase agreement (PPA), or electricity power agreement, is a long-term contract between an electricity generator and a customer, usually a utility, government or company. PPAs may last anywhere between 5 and 20 years, during which time the power purchaser buys energy at a pre-negotiated price.
Ice storage air conditioning
Ice storage air conditioning is a form of thermal energy storage in which cooling capacity is stored by freezing water and recovered later by melting the ice. In building applications, the storage can be charged when cooling demand or electricity prices are lower and discharged during periods of higher cooling demand,…
Rooftop solar power
A rooftop solar power system, or rooftop PV system, is a photovoltaic (PV) system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters…
List of largest power stations in the United States
This article lists the largest electricity generating stations in the United States in terms of installed electrical capacity. Non-renewable power stations are those that run on coal, fuel oils, nuclear, natural gas, oil shale, and peat, while renewable power stations run on fuel sources such as biomass, geothermal…
List of geothermal power stations
This is a list of operational geothermal power stations with a current installed capacity of at least 10 MW. The Geysers in California, United States is the largest geothermal power station in the world, with a nameplate capacity of 1,590 MW and an annual generation of 6,516 GWh in 2018.
Energy conservation
Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less and better sources of energy for continuous service) or changing one's behavior to use less and better source of service (for example, by driving…
Solar panel
A solar panel is a device that converts sunlight into electricity by using multiple solar modules that consist of photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light.
