Companies in the alternative energy sector are looking for energy that doesn’t use up the earth’s natural resources. They avoid energy consumption that harms the environment.
Fossil fuels such as oil and gas and or nuclear power have been the dominant sources of energy for centuries. But now alternative measures are taking preference in an effort to reduce climate change and global warming.
Alternative energy also means sustainable energy or renewable energy. This includes hydro-power, wind-power and solar power. Companies working in this area develop products that convert hydro, wind and solar into energy.
Examples include Sunpower Inc, Seaformatics, and Vestas Wind Systems.
