Solar explained
People have used the sun''s rays (solar radiation) for thousands of years for warmth and to dry meat, fruit, and grains. Over time, people developed technologies to collect solar energy for
How Does Solar Work?
While every location on Earth receives some sunlight over a year, the amount of solar radiation that reaches any one spot on the Earth''s surface varies. Solar technologies capture this
Climate and Earth''s Energy Budget
The Earth''s climate is a solar powered system. Globally, over the course of the year, the Earth system—land surfaces, oceans, and atmosphere—absorbs an average of
Solar 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 source that,

Beginning with the surge in coal use, which accompanied the Industrial Revolution, energy consumption steadily transitioned from wood and biomass to fossil fuels. The early development of solar technologies starting in the 1860s was driven by an expectation that coal would soon become scarce. However, development of solar technologies stagnated in the early 20th century in the f
The Sun''s Energy: An Essential Part of the Earth System
Without the Sun, life on Earth would not be possible. The energy we receive from the Sun provides light and heat, drives our planet''s winds and ocean currents, helps crops grow, and
