The energy that fuels the world
There are 2 types of energy – Renewable and Non-Renewable. 75% of the energy we use comes from non-renewable energy such as oil, fossil fuels, coal, natural gas and nuclear energy. These are energy sources that cannot be replenished if they run out. Our wish is that one day, the whole planet switches to using renewable instead. This is a type of energy that is not only environment friendly but is inexhaustible (well, it may run out but not for a very long time yet.) Examples of renewable energy are solar, water, bioenergy, ocean, wind and geothermal power.

The electricity that powers the planet is a secondary energy that can come from any of these sources. Can you imagine what will happen if we run out of an energy source? The world will go dark, transportation will come to a halt and you’ll have no power to even charge your mobile phone. That’s how dependent we are on our energy… and to date, we have not fully developed our use of renewable energy sources to replace fossil fuel.
Here are more interesting energy facts:
- Everything around you is Energy. It can come in different forms – mechanical, thermal, radiant, electrical, chemical or nuclear.
- Renewable energy is a form of clean energy that is provided by natural sources in nature.
- Sustainable energy is energy which can be replenished in a human lifetime and doesn’t cause long term damage to the environment.
- Burning of fossil fuels is a major contributor to Global Warming. It is expected that the planet’s temperature may rise at least another 2 degrees Fahrenheit up to 11 degrees in the next 100 years.

- One wind turbine can produce enough electricity to power up to 300 homes!
- Biomass is now the largest source of renewable energy in the US. There are 200 existing plants giving electricity to 1.5 million American homes.
- Fossil Fuels are being burned faster than they are formed. Experts are predicting that it will run out soon.
- Oil is still the largest source of primary energy worldwide.
