Uses Of Renewable Energy

The technology used to harvest the sun s energy is constantly evolving including water heating rooftop pipes photo voltaic cells and mirror arrays.

Uses of renewable energy.

Sunlight or solar energy can be used for heating lighting and cooling homes and other buildings generating electricity water heating and a variety of industrial processes. Renewable energy is energy that is collected from renewable resources which are naturally replenished on a human timescale such as sunlight wind rain tides waves and geothermal heat. The demand for nuclear energy decreased in part due to nuclear disasters three mile island in 1979 chernobyl in 1986 and fukushima in 2011. Renewable energy usable energy derived from replenishable sources such as the sun solar energy wind wind power rivers hydroelectric power hot springs geothermal energy tides tidal power and biomass biofuels.

In this interactive chart we see the share of primary energy consumption that came from renewable technologies the combination of hydropower solar wind geothermal wave tidal and modern biofuels traditional biomass which can be an important energy source in lower income settings is not included. At its core every source of energy even fossil fuels were originally powered by seemingly omnipresent solar energy. Renewable energy often provides energy in four important areas. Since then the amounts and the percentage shares of total u s.

As a result renewable energy prices can be very stable over time. Several forms have become price competitive with energy derived from fossil fuels. Primary energy sources include fossil fuels petroleum natural gas and coal nuclear energy and renewable sources of energy. The united states uses and produces many different types and sources of energy which can be grouped into general categories such as primary and secondary renewable and nonrenewable and fossil fuels.

Electricity generation air and water heating cooling transportation and rural off grid energy services. Moreover the costs of renewable energy technologies have declined steadily and are projected to drop even more. Renewable energies are sources of clean inexhaustible and increasingly competitive energy they differ from fossil fuels principally in their diversity abundance and potential for use anywhere on the planet but above all in that they produce neither greenhouse gases which cause climate change nor polluting emissions their costs are also falling and at a sustainable rate whereas the. Although renewable facilities require upfront investments to build they can then operate at very low cost for most clean energy technologies the fuel is free.

Solar energy is a versatile and renewable source of energy. The use of oil and natural gas also had considerable growth followed by hydropower and renewable energy. Hydropower and wood were the most used renewable energy resources until the 1990s. In the home solar energy can be used to warm water for bathing or cleaning in the same way that solar bags are used among camping enthusiasts.
