  2. Re-cap… • What are some examples of renewable resources? • What is one of the largest forms of renewable energy in Ontario? • What are some examples of non-renewable resources?

  3. Renewable energy resource: Hydroelectricity • Hydroelectricity dams create electricity by having a flow of water turn a generator • A generator is a device that can create electricity, if it can be made to spin. The water needed to spin the generator usually comes from a river, that has been blocked by a dam • The water that is blocked by the dam is called a reservoir, and this ensures that there will always be water available to turn the generators and make electricity • Electricity is then carried from transmission lines to cities in Canada • Electrical generators operate without creating air pollution and are reasonably cheap to operate • Large dams needs for electricity are very expensive , and they only can be built in certain areas. Once the dam is built, the reservoirs can destroy local ecosystems and dams

  4. What are some negative impacts of hydroelectricity?

  5. Renewable energy resource: Solar energy • Solar energy uses energy from the sun and and transforms it into other forms of energy. For example, the sun could be used to heat water for showers, washing dishes, and other household needs. This is called passive solar heating • Active solar heating occurs when solar energy is used in conjunction with other electrical devices • Solar energy is available wherever the sun is, and can be used to create electricity while not causing pollution

  6. What do you think would be a negative aspect of solar energy?

  7. Renewable energy source: wind • Collecting energy from the wind require a windmill, turbine, or blade to catch and turn in the wind • The four most common type are: multiblade, two or three blade high speed motor and vertical axis wind generator • Wind is free and they do not cause any pollution, they also can be set up faster than dams or coal power plants • However, wind speed is variable and birds can be killed by flying into them

  8. What do you think are some complications of wind energy?
