2023 saw a step change in renewable capacity additions, driven by China''s solar PV market. Global annual renewable capacity additions increased by almost 50% to nearly 510 gigawatts (GW) in 2023, the fastest growth rate in the past two decades. This is the 22nd year in a row that renewable capacity additions set a new record.
Solar energy is radiant energy from the sun—a fully renewable energy resource. We use the solar resource to provide daylight, electricity, and heat in four ways (in order of prevalence): Indirect: Our primary use of the sun''s energy is for free light and warmth (not counted in the data below but important for energy efficiency) Solar PV
Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun''s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of
Solar PV accounted for 4.5% of total global electricity generation, and it remains the third largest renewable electricity technology behind hydropower and wind. China was responsible for about 38% of solar PV generation growth in 2022, thanks to large capacity additions in 2021 and 2022.

The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest, 122 PW, is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth''s surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet. Most of the world''s pop
Yes, solar energy is a renewable energy source. Renewable energy sources are those that can be replenished naturally and are not depleted when used. They include: The sun is an abundant and
Renewable energy is energy from sources that are naturally replenishing but flow-limited; renewable resources are virtually inexhaustible in duration but limited in the amount of energy that is available per unit of time. The major types of renewable energy sources are: Download image U.S. primary energy consumption by energy
Solar energy is a form of renewable energy, in which sunlight is turned into electricity, heat, or other forms of energy we can use. It is a "carbon-free" energy
Solar Futures Study. The Solar Futures Study explores solar energy''s role in transitioning to a carbon-free electric grid. Produced by the U.S. Department of Energy Solar Energy Technologies Office (SETO) and the National Renewable Energy Laboratory (NREL) and released on September 8, 2021, the study finds that with
Solar power is generated in two main ways: Solar photovoltaic (PV) uses electronic devices, also called solar cells, to convert sunlight directly into electricity. It is one of the fastest
Even without climate change, fossil fuels are a finite resource, and if we want our lease on the planet to be renewed, our energy will have to be renewable.
In 2022, 32% of Australia''s total electricity generation was from renewable energy sources, including solar (14%), wind (11%) and hydro (6%). The share of renewables in total electricity generation in 2022 was the highest on record, a share 1 percentage point higher than the earlier 2021-22 financial year.
Global renewable capacity is expected to increase by almost 2 400 GW (almost 75%) between 2022 and 2027 in the IEA main-case forecast, equal to the entire installed power capacity of the People''s Republic of China (hereafter "China"). Renewables growth is propelled by more ambitious expansion policies in key markets, partly in response to

SETO resources can help you figure out what''s best for you when it comes to going solar. Consider these questions. There are a number of mapping services that have been developed by SETO awardees that will help you determine if your roof is suitable for solar and can even provide you with quotes from pre-screened solar providers in your area.
Solar power is energy from the sun that is converted into thermal or electrical energy. Solar energy is the cleanest and most abundant renewable energy source available, and the U.S. has some of the richest solar resources in the world. Solar technologies can harness this energy for a variety of uses, including generating electricity, providing light or a
4 · In contrast, renewable energy sources accounted for nearly 20 percent of global energy consumption at the beginning of the 21st century, largely from traditional uses of biomass such as wood for heating and
