Hydro Power (water energy)
- http://www.sciencekids.co.nz/sciencefacts/energy/hydropower.html where I got the power stations.
- Water Energy is energy used in dams
- The water is used in generators and in the generator creates Energy. The energy is then sent into power lines. Then we get power in our home, cell phones, lights, Tv, etc.
- In 2006 hydroelectricity supplied around 20% of the worlds electricity.
Most hydroelectric power stations use water held in dams to drive turbines and generators which turn mechanical energy into electrical energy.
- A small number of countries produce their electricity through hydropower
- The largest hydroelectric power station is in China

- http://interestingenergyfacts.blogspot.com/2008/03/solar-energy-facts.html Website I go information from
- Solar Energy ~ can be renewable
- Free and clean energy source
- Using the suns energy for practical purposes
- "Solar power"
The largest solar power plant in the world is found in the Mojave Desert, USA.
- Solar cells are also called photovoltaic cells
- Can be used in calculators
- Almost noise free
- In one technique, long troughs focus sunlight on a pipe of oil that runs through the middle. The hot oil then boils helping to make a generator.http://environment.nationalgeographic.com/environment/global-warming/solar-power-profile/
The thing that makes these two energies the same is that they both help the world by,
- They both give power to power lines
- Both very important to the world
- Renewable energy
- Used from the sun
- Clean and fresh
- Used for different purposes
- Controls many things
- Used in dams
- Powers power lines
