Explore renewable energy solutions that harness sun, wind, water, and more to accelerate the energy transition and cut emissions. In the 21st century, as countries race to cut greenhouse gas emissions to curb the unfolding climate crisis, the transition to renewable energies has become a. . There are two main types of solar energy technologies—photovoltaics (PV) and concentrating solar-thermal power (CSP). On this page you'll find resources to learn what solar energy is; how you, your business, or your community can go solar; and find resources for every step of the way. Solar power is generated in two main ways: Solar photovoltaic (PV) uses electronic devices, also called solar cells, to convert sunlight directly into electricity. Using solar energy can have a positive, indirect effect on the environment when solar energy replaces or reduces the use of other energy sources that have larger effects on the environment.
