How to Green-up Your Home



Sustainable green energy is energy that is consumed at insignificant rates compared to its supply and with manageable collateral effects, especially environmental effects. Another common definition of sustainable green energy is an energy system that serves the needs of the present without compromising the ability of future generations to meet their needs.[1] The organizing principle for sustainability is sustainable development, which includes the four interconnected domains: ecology, economics, politics and culture.[2] Sustainability science is the study of sustainable development and environmental science.[3]

Technologies that promote sustainable green energy include renewable energy sources, such as hydroelectricitysolar energywind energywave powergeothermal energybioenergytidal power and also technologies designed to improve energy efficiency. Costs have fallen dramatically in recent years, and continue to fall. Most of these technologies are either economically competitive or close to being so. Increasingly, effective government policies support investor confidence and these markets are expanding. Considerable progress is being made in the green energy transition from fossil fuels to ecologically sustainable systems, to the point where many studies support 100% renewable green energy.
