I was interested in this topic because there has been a lot of chatter about energy lately, and I wanted to learn more about it by researching about the different types of energy.
What I want to figure out is the different types of energy. .

What I want to know:

  • How many different types of renewable resources are there?
  • What alternate energy source has the greatest amount of energy?

A list of Alternate Energies:

  • Hydroelectric
  • Solar
  • Wind
  • Nuclear
  • Bioenergy





Hydroelectric Energy:

  • Hydroelectric energy is made when when water is run through turbines in a dam of a river (See video below) The force of water spins the turbines, which spins turbines, which produces electricity. Since dams have large reservoirs, electricity can be produced nonstop.

Solar Energy: external image ast016.gif

  • Solar Energy can be used in several different ways for a business or home. The most commonly used application is using Solar Energy to heat hot water. This technology can significantly reduce the amount of oil, gas, or electricity used to heat water.
  • Solar Electricity, is an application of solar energy with many choices. Solar cells convert sunlight into electricity which can be used to power most appliances in a home, the same as being recycled into the utility grid.


This was pretty cool:

Wind Energy

  • Wind energy is produced when wind spins the blades of a turbine. The turbine then turns a generator that creates electricity. Since wind speeds are not constant, wind power is not that trustworthy. Large numbers of wind turbines are needed to generate enough electricity, making wind power expensive and unattainable. Propeller type windmills are best for collecting wind energy.

Nuclear Energy

  • Nuclear power is created when atoms are splitted, and not by burning fuel.
  • There are currently over 400 nuclear power stations around the world. Together they produce about 16% of the whole world's electricity.


  • Wood is currently the world's oldest and most common type of bioenergy. The amount of wood can be maintained if greater amounts of trees are planted after they are cut down, and harvested.
  • Unfortunately, in multiple parts of our planet, wood is being burned faster than it is replaced. Fortunately, there are lots of other plants that are able to be grown on a large scale to provide us with energy.

Here's an essay that I wrote for connections that has to do with alternate energy:
