Concentrating Solar Power: Energy from Mirrors

This abundance of solar energy makes concentrating solar power plants an attrac- tive alternative to traditional power plants, which burn polluting fossil fuels such as oil and coal. Fossil...

Solar Photovoltaic Cell Basics | Department of Energy

When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the “semi” means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal. There are several different semiconductor materials used in PV cells. When the semiconductor is exposed to light, it absorbs the light’s energy and transfers it to negatively charged particles in the material called ele ...

Solar Energy Basics | NREL

Solar energy is a powerful source of energy that can be used to heat, cool, and light homes and businesses. More energy from the sun falls on the earth in one hour than is used by everyone in the world in one year. A variety of technologies convert sunlight to usable energy for buildings. The most commonly used solar technologies for homes and businesses are solar photovoltaics for electricity, passive solar design for space heating and cooling, and solar water heating. Businesses and industry use solar technologies to diversify their energy so ...

Actions and measures on energy prices

In the EU, each country determines its energy mix, in compliance with internal market rules and taking into consideration our climate ambition. The primary objective of a well-functioning energy market is to foster a secure supply of energy, produced as sustainably as possible and at affordable prices. In the second half of 2021, the EU saw a significant increase in wholesale gas prices. One of the main drivers was the surge in global energy demand, as economic activity picked up after the Covid-19 pandemic. This led to tighter supply, resultin ...
