Solar energy comes from the sun’s radiation.

There are two types of energy: 1. Passive solar energy for example may

come from constructing a building to face the sun which will catch the sun’s heat through the windows. 2.Active Solar energy for example gets sunlight and turns it into electrical energy.

Advantages: Environmentally Friendly Economically Beneficial Easily Accessible

Disadvantages: Coast Large area for solar panels Pollution to panels Only useful during the day

This energy is a heating of our oceans, earth, and atmosphere by the sun.

Wind is used to generate mechanical power or electricity.

Advantages: Free Renewable resource Clean Non-polluting Electricity

Disadvantages: Unreliable More turbines being needed to make a

bigger impact. It cost’s a lot of money to build more

turbines. In the process of building turbines it

could endanger animals

Hydropower is the most important renewable source of energy.

These are some of the largest producers

of hydropower: China, Canada, Brazil, and the United States

Advantages: Renewable Water provided by nature Helps reduce green house gas Low costs

Disadvantages: Very high investment costs Precipitation Loss of fish habitat

Geo means the Earth. Thermal means Heat. So the Earths

Heat.

Geo Thermal

Erath Heat

Advantages: Significant Cost Saving Reduce Reliance on Fossil Fuels Environmental Benefits Direct Use Job Creation and Economic Benefits

Disadvantages: Not Widespread Source of Energy High Installation Costs Can Run Out of Steam Suited To Particular Region May Release Harmful Gases

Biofuels are made of mixed biological material.

Biofuels can be made of relatively any

from ethanol, vegetable oil, wood, and even algae

Advantages: They are non-toxic Renewable Biodiesel is biodegradable

Disadvantages: Biofuels may raise the price of some

certain foods. Heavily dependent on Oil Soil erosion will grow

Advantages: Nuclear power is reliable Produces small amounts of waste Does not contribute to the green house

affect.

Disadvantages: A lot of money for safety

It can be a disaster if it grows wrong

Very dangerous

I think that Biofuels are the best out of the six because it is non-toxic, renewable, and it does not let out green house gases also safer for the environment.
