Designated commodity or resource, such as solar energy, biodiesel fuel, or firewood, that is inexhaustible or replaceable by new growth.
Energy sources that cannot be depleted, such as solar power, wind, hydro, biomass, etc. The opposite of fossil fuel energy sources.
A source of energy that is replenished by natural phenomena, such as firewood or the water held behind by a dam used for hydroelectrical purposes. Conversely, fossil fuels are a non-renewable source of energy.
There is no formal definition for this term. Typical usage defines it as any energy source that is replenished at least as fast as it is used. Standard examples are solar, wind, hydroelectric, and biomass products.
Energy obtained from sources that essentially are inexhaustible, unlike fossil fuels, for example, of which there are a finite supply. Renewable energy sources include wood, waste, photovoltaic and solar thermal energy.
Energy that is derived from sources such as wind, solar, hydroelectric or geothermal resources. Environmentally friendly.
Includes energy that comes from sources such as the sun, wind, waves, tides, ocean currents, the hydrological cycle, biomass and geothermal sources.
Renewable types of energy include solar power, windpower and hydropower and different types of biofuel. The basic feature of renewable energy is that it can be re-created within a foreseeable period, with the exception of the sun which constantly generates energy (if we disregard the fact that many billions of years from now the sun will disappear).
Energy resources that are produced naturally as fast as they are consumed, such as solar, wind, and hydroelectric power.
An energy source that, from an Earth perspective, is continually replenished.
Includes technologies such as solar energy, wind power, low head hydro power, geothermal energy, landfill- and mine-based methane gas, energy from waste, and sustainable biomass energy.
Energy obtained from sources that are essentially inexhaustible, unlike fossil fuels. It includes conventional hydro-electric, wood, bio-feedstocks, waste, geothermal, wind, photovoltaic, and solar thermal energy.
Renewable energy is energy that comes from a renewable energy source such as solar, wind, hydro, geothermal, biomass, and tidal.
The term renewable energy covers those resources that occur and reoccur naturally in the environment. Sources include solar, wind, biomass and wave/ hydroelectric power.
The term used to cover those energy flows that occur naturally and repeatedly in the environment - energy from the sun, the wind and the oceans, and the fall of water. Plant material is an important source of renewable energy. Combustible or digestible industrial, agricultural and domestic waste materials are also normally regarded as renewable sources of energy.
An energy source that renews itself. Fossil fuels, once consumed, are gone forever. In contrast, solar energy is renewable. The sun we harvest today has no effect on the sun we can harvest tomorrow. Renewable energy is produced from regenerative or virtually inexhaustible resources such as biomass, solar radiation, the wind, water, or heat from the Earth's interior. Renewable energy is also defined as energy created by sources that are not used up or depleted. Most forms of renewable energy do not produce carbon dioxide and other harmful gases. Using more renewable energy sources would reduce carbon dioxide emissions and minimize global warming.

Renewable energy generally refers to energy derived from non-fossil fuel resources (excluding nuclear). It often includes wind, photovoltaics, biomass and hydro. However, the definition may vary in different part of the county and in situations in which new energy technology development is being promoted (e.g., hydro may be excluded).
Energy flows that occur naturally and repeatedly in the environment, for examples, sun, wind, ocean, fall of water, geothermal, combustible waste.
Renewable Energy refers to energy derived from renewable sources including sunlight, wind, waves, tides and biomass. With regard to solar energy, for instance, one may typically need to address the following issue: "Does the purchase and installation of a solar heating system for this application, in this location, constitute a sound investment?" Overall, renewable energy may involve the following disciplines: engineering; renewable energy system design; project management; wind power and micro/mini hydro power technology management; solar cell and electronics development; and solar cell and solar module manufacturing.

Renewable energy is energy flows that occur naturally and repeatedly in the environment, for example from the wind, water flow, tides or the sun.
The term 'renewable energy' covers those resources which occur and recur naturally in the environment. Such resources include heat from the earth or the sun, power from the wind and from water and energy from plant material and from the recycling of domestic, industrial or agricultural waste.
Renewable energy sources are those which do not require the use of limited fossil fuel resources. They include wind power, hydroelectric or geothermal power and photovoltaics. They can often be used to produce hydrogen for use in fuel cells.
sources that capture their energy from existing flows of energy, from on-going natural processes, such as sunshine, wind, flowing water, biological processes, and geothermal heat flows. Neither fossil fuels nor nuclear power are considered to be renewable.
energy generated from sources other than finite fossil fuel reserves
Resources that constantly renew themselves or that are regarded as practically inexhaustible. These include solar, wind, geothermal, hydro and wood. Although particular geothermal formations can be depleted, the natural heat in the earth is a virtually inexhaustible reserve of potential energy. Renewable resources also include some experimental or less-developed sources such as tidal power, sea currents and ocean thermal gradients.
Energy produced by non fossil fuel or nuclear means. Includes energy produced from PV, wind turbines, hydro-electric and biomass.
Energy derived from resources that are regenerative. Examples include photovoltaic (solar energy), wind power, or hydroelectric power.
Renewable energy includes solar power, wind, wave and tide, and hydroelectricity. Solid renewable energy sources consist of energy crops, other biomass, wood, straw and waste, whereas gaseous renewables consist of landfill gas and sewage waste.

Renewable energy comes from sources that can be replenished on a human time scale, such as biomass (wood), or that are essentially inexhaustible, such as waste and geothermal, wind, and solar energy. Fossil fuels are non-renewable energy sources; there is a finite supply of them. Renewable energy is also often clean energy; it can be generated with few or zero emissions and little to no environmental damage.

Renewable energy is defined as "energy derived from resources that are regenerative or for all practical purposes can not be depleted."United States Department of Energy http://www.eere.energy.gov/consumer/information_resources/index.cfm/mytopic=60001#R Glossary of energy-related terms (URL accessed Dec 21, 2006) Renewable energy sources contribute approximately 29.3% of human energy use worldwide. The prime source of renewable energy is solar radiation, i.e. sunlight. The Earth-Atmosphere system supports approximately 5.4 x 1024 joules per year in the solar radiation cycle (Sorensen, 2004).
