Define sustainable energy

Energy Sustainability with a Focus on Environmental Perspectives

A general definition can perhaps be developed by extending definitions of sustainability or sustainable development. For instance, Kutscher et al. define sustainable energy as energy produced and used in such a way that it "meets the needs of the present without compromising the ability of future generations to meet their own needs."

OverviewDefinitions and backgroundEnergy conservationSustainable energy sourcesEnergy system transformationGovernment policiesFinance

Energy is sustainable if it "meets the needs of the present without compromising the ability of future generations to meet their own needs." Definitions of sustainable energy usually look at its effects on the environment, the economy, and society. These impacts range from greenhouse gas emissions and air pollution to energy poverty and toxic waste. Renewable energy sources such as

Energy | Definition, Types, Examples, & Facts | Britannica

Energy can be neither created nor destroyed but only changed from one form to another. This principle is known as the conservation of energy or the first law of thermodynamics.For example, when a box slides down a hill, the potential energy that the box has from being located high up on the slope is converted to kinetic energy, energy of motion. As

Sustainable Energy: Sources, Definition & Examples

Sustainable energy refers to the use of any type of energy that can meet demands without putting the resources in danger of running out. Sustainable energy sources cause minimal damage to the environment and will never

Renewables

Renewables, including solar, wind, hydropower, biofuels and others, are at the centre of the transition to less carbon-intensive and more sustainable energy systems. Generation capacity has grown rapidly in recent years, driven by policy support and sharp

Why Clean Energy Matters

Renewable energy resources provide an affordable, reliable, and sustainable U.S. power supply—while also reducing the country''s greenhouse gas emissions. We can harness abundant domestic resources including wind energy, solar energy, bioenergy, geothermal energy, hydropower, and marine energy to reduce our reliance on fossil fuels.

Sustainability | Description, Theories, & Practices | Britannica

Sustainability is at the core of concepts such as sustainable yield, sustainable society, and sustainable development. The term sustainable yield refers to the harvest of a specific (self-renewing) natural resource—for example, timber or fish. Such a yield is one that can in principle be maintained indefinitely because it can be supported by the regenerative

What is green energy? | Clean and renewable energy

What is the definition of green energy? Green energy is energy that can be produced using a method, and from a source, that causes no harm to the natural environment. Renewable energy is also often called sustainable energy. A renewable energy source may not be considered ''green'' if, for example, some carbon emissions are associated

Renewable Energy

It remains an important source in lower-income settings today. However, high-quality estimates of energy consumption from these sources are difficult to find. The Energy Institute Statistical Review of World Energy – our main data source on energy – only publishes data on commercially traded energy, so traditional biomass is not included.

Energy sustainability: a definition and assessment model

Energy is the fundamental component of all economic activity and a central ingredient of international politics. Energy is finite and often creates externalities. A fundamental question then arises about its sustainability. Assessing energy sustainability is important since energy is a key factor of all economies. However, energy generation imposes large pressures
