What are the differences between energy efficiency, clean energy and renewable energy?  Energy efficiency is a measurement for the rate at which energy is used. In homes and buildings, residents and office workers should want to lower their energy usage to save on utility bills and can do so by making their home or building more energy efficient, which means lowering the amount at which the home or building uses energy on a daily, monthly or annual basis.

  • Clean energy is known as the various ways in which energy can be produced and supplied in clean manners. Clean energy includes solar energy, thermal energy, wind energy and other forms of energy generation that use none or very little natural resources like oil, coal and natural gas.
  • Renewable energy is known as energy produced from renewable resources, such as solar energy from the sun, wind energy and hydropower that uses water to produce energy.
  • Energy efficiency and renewable energy are both considered parts of clean energy.

What about fossil fuels?  Currently, fossil fuels provide around 66 percent of the world’s electrical power, and 95 percent of the world’s total energy demands (heating, transport, electricity generation, etc.).  These power plants burn the fossil fuels to make our electricity and in that process greenhouse gas is made, including carbon dioxide and methane.

To some, clean energy also means nuclear energy.  Clean energy technologies are generally defined as those that:

  • Reduce energy consumption
  • Do less harm to the environment
  • Increase the supply of renewable energy to enable the transition to a renewable-based energy economy
  • Improve the efficiency of energy use in homes or industry
  • Improve the processes and systems that use energy
  • Enable energy solutions to infiltrate the marketplace
