Green Energy

Sustainable Energy

Since energy use and production contribute over 88% of the greenhouse gas emissions, pragmatic changes in the energy sector have the potential to reduce emissions significantly. Many policy initiatives now promote sustainable energy or green energy options. 

The concept of sustainable energy or green energy embraces practices, policies, and technologies that provide energy at the least financial, environmental and social costs. When these costs are factored in calculating life-cycle costs for fossil fuels, sustainable energy options make an even more compelling case for long-term strategic applications.

Even if new sources of energy appear quickly, people would have to rely on fossil fuels for many years. During this period there are three main things that can be done: 1) using limited energy resources more efficiently, 2) increasing the use of renewable energy sources, and 3) shifting from more carbon- to less carbon-intensive fuels, for instance, from coal to oil to natural gas.
