Renewable energy (or green energy) is energy from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider nuclear power a renewable power source, although this is controversial. Rene
alternative energy, Any of various renewable power sources to use in place of fossil fuels and uranium. Fusion devices ( see nuclear fusion) are believed by some to be the best long-term option, because their primary energy source would be deuterium, abundant in ordinary water. Other technologies include solar energy, wind power, tidal power
The term "renewable" encompasses a wide diversity of energy resources with varying economics, technologies, end uses, scales, environmental impacts, availability, and depletability. For example, fully "renewable" resources are not depleted by human use, whereas "semi-renewable" resources must be properly managed to ensure long-term

Alternative Energy refers to energy sources other than fossil fuels. This includes all renewable sources and nuclear. Nuclear is not classified as a renewable energy source. A renewable energy source is produced from sources that do not deplete or can be replenished 1 within a human''s lifetime. Nuclear is produced from mined elements like
The energy sector is undergoing a profound and complex transformation as the shift to renewable energy gathers momentum. Transitioning the electricity system to deal with an increasing share of renewables and different ways of operating is challenging, but it presents many opportunities to help businesses manage their energy costs, as well
Types of Renewable Energy Sources. Hydropower: For centuries, people have harnessed the energy of river currents, using dams to control water flow.
The quest for alternative energy sources (e.g., geothermal, nuclear, solar, wind, hydroelectric) is characterized by intense debate that in time will involve governments,
Types of renewable energy sources. Hydropower: For centuries, people have harnessed the energy of river currents, using dams to control water flow.
Alternative energy definition: energy, as solar, wind, or nuclear energy, that can replace or supplement traditional fossil-fuel sources, as coal, oil, and natural gas.. See examples of ALTERNATIVE ENERGY used in a sentence.
Abstract. Alternative energy sources are regarded as "clean," which refers to the fact that they don''t emit harmful pollutants or increase carbon footprint. It comprises all forms of renewable
Renewable energy sources include solar, wind, hydropower, geothermal energy, and biomass fuels. These energy sources are sustainable and generate fewer greenhouse gas emissions than fossil fuels. Renewable and nonrenewable energy sources. Clockwise from top left: a solar power station, a wind farm, a hydroelectric power plant, and a coal-fired
Naturally, there is some debate as to what "alternative energy" means and what it can be applied to. On the one hand, the term can refer to forms of energy that do not increase humanity''s
But investments in renewable energy will pay off. The reduction of pollution and climate impacts alone could save the world up to $4.2 trillion per year by 2030. Moreover, efficient, reliable
