Answer:
Explanation:
Clean. Green energy, which includes green electricity, is clean energy. This means it is produced with little-to-no environmental impact and does not dispense greenhouse gases into the air that contribute to global warming, the way fossil fuels do.
Varied.Green energy sources include wind, geo-thermal, hydro, and solar energy. Wind and hydro sources generate energy through the movement of air and water, while geo-thermal and solar sources generate energy through heat. All, however, provide reliable energy and protect the environment.
Renewable. As stated above, green energy sources eliminate the emission of greenhouse gases into the air. These sources are also renewable energy sources - meaning they are not created from finite materials like fossil fuels.
Stable. Green energy's varied forms mean more locations across the planet have the potential to harvest this renewable energy. This means more energy can be collected right here in the United States, making the country less dependent on energy from foreign countries.
Inexpensive. As the demand for green energy continues to grow, the price continues to drop thanks to economics of scale. Consider this: between the years 2010 and 2012 the costs associated with producing energy from wind dropped by 20 percent, and prices have fallen by more than 80 percent since 1980.
Right for You. You've seen the environmental and economic benefits that come from turning your home into a green home. The good news is, those benefits will increase as green energy continues to gain popularity in the market. If you're ready to make the switch to renewable energy, see what Direct Energy has to offer.

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.
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.
