For the full article, see solar energy . solar energy, Radiation from the Sun that can produce heat, generate electricity, or cause chemical reactions. Solar collectors, such as those used for solar water heating, collect solar radiation and transfer it as heat to a carrier fluid. It can then be used for heating.
Solar power is a type of energy with great future potential-even though at present it covers merely a minor portion of global energy demands (0.05% of the total primary energy supply); at the moment PV power generates less than 1% of total electricity supply.
power from the sun that requires no other energy or mechanical system. process by which plants turn water, sunlight, and carbon dioxide into water, oxygen, and simple sugars. able to convert solar radiation to electrical energy. chemical or other substance that harms a natural resource. very powerful.
Solar energy potential Earth's photovoltaic power potential. The potential for solar energy to be harnessed as solar power is enormous, since about 200,000 times the world’s total daily electric-generating capacity is received by Earth every day in the form of solar energy.
Solar energy is the thermal radiation of the sun. The amount of solar energy that illuminates the earth is very large. The energy produced by the sun illuminating the earth in 40 min is equivalent to the total amount of energy consumed by humans all over the world. It can be said that solar energy is inexhaustible.
