Answer:
Sustainable energy is 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."[1] It is similar to the concepts of green energy and clean energy in its consideration of environmental impacts, however formal definitions of sustainable energy also include economic and social impacts.
Explanation:
the energy transition to meet the world's needs for electricity, heating, cooling, and power for transport in a sustainable way is widely considered to be one of the greatest challenges facing humanity in the 21st century. production and consumption of energy emits over 70% of human-caused greenhouse gas emissions. worldwide, nearly a billion people lack access to electricity, and around 3 billion rely on smoky fuels such as wood, charcoal or animal dung to cook. these and fossil fuels are a major contributor to air pollution, which causes an estimated 7 million deaths per year.
in general, renewable energy sources such as solar, wind, and hydroelectric energy are widely considered to be sustainable. however, aspects of some renewable energy projects, such as the clearing of forests for the production of biofuels, can lead to similar worse environmental damage than using fossil fuel energy. nuclear power is a low-carbon source and has a safety record comparable to wind and solar,[2] but radioactive waste and the risk of major accidents are disadvantages of this technology.
moderate amounts of wind and solar energy, which are intermittent energy sources, can be integrated into the electrical grid without additional infrastructure such as grid energy storage and demand-response measures. these sources generated 8.5% of worldwide electricity in 2019, a share that has grown rapidly.[3] costs of wind, solar, and batteries are projected to continue falling due to innovation and economies of scale from increased investment.
proposed pathways for limiting global warming to 1.5 °c describe rapid implementation of low-emission methods of producing electricity and heat, and a shift towards more use of electricity in sectors such as transport. the pathways also include measures to reduce energy consumption; and use of low-carbon fuels, such as hydrogen produced by renewable electricity or with carbon capture and storage. achieving these goals will require government policies including carbon pricing, energy-specific policies, and phase-out of fossil fuel subsidies.

Answer:
Energy is a valuable resource, which can be used to give energy to various industries. In a world where manufacturing plays an important role in the country, energy provides the ability for a system to function, without energy no industry can function.
Green energy is a well-known energy source in many countries such as the United States, China, Germany, and Spain, etc.
Green energy comes from a natural source such as sunlight, wind & geothermal heat.
The earliest use of green Energy dates back to 2000 BC when coal mining was used by the Chinese. they would burn the coal as a source of heat and cooking.
Green energy is the energy that can be used in a big way without damaging the environment. it is environmentally friendly and empowers various systems while releasing little or no toxic substances into the atmosphere.
Green energy can also be defined as renewable energy that can be used for generation.
Green energy is considered Clean Energy due to the lack of negative impact on the environment. it is one of the alternative energy sources that has received special attention from the government and various National Organisation to keep the planet clean.
Green energy is also sometimes referred to as energy derived from the processing of waste materials in an effort to make the environment cleaner.
Such material pollutes and the environment by increasing the amount of waste and toxic substances on the surface of the earth.
Example of waste material used for energy production includes sewage, animal waste, municipal solid waste, industrial waste, etc
.
Most of these waste materials are used to make biogas as green energy. By processing waste material and using them to provide energy and environment is made cleaner.
The need to move to green energy sources has attracted attention from many world leaders. Green energy is an ideal way to reduce the effect of global warming and create a clean and healthy environment.
