2  Renewable energy is energy made from natural sources (Source: plans/alternative-energy-sources)http://www.wecanchange.com/high-school/resources/lesson- plans/alternative-energy-sources

3  is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat.[2]Renewable energy replaces conventional fuels in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off- grid) energy services.  (source:

4  The five renewable sources used most often are:  Biomass  Geothermal  Water (Hydropower)  Wind  Solar

5  Is energy derived from plants and animals.  Biomass comes in many forms, the most common being wood.  When we use plants as a source of energy we are converting their stored energy from the sun.  Using the methane gas given off by landfills and animal waste is also becoming more common.  Another increasingly popular form of biomass is in the form of biofuels such as ethanol and biodiesel, which is also derived from plants and animals.  Source of the texts:  Source of images and photos: https://images.google.com/https://images.google.com/

6  Uses heat generated by the earth’s interior. By drilling down into the Earth’s crust, much like we drill for oil, we can use that heat to generate electricity. Geothermal is a good source for heating homes and buildings.  Source of the texts:  Source of images and photos: https://images.google.com/https://images.google.com/

7  The energy contained in running water can be turned into electricity. Water, which is impounded or held behind a dam, is released through a turbine that spins a generator producing electricity.  Source of the texts:  Source of images and photos: https://images.google.com/https://images.google.com/ 

8  As the wind blows it spins the large blades on a wind turbine and generates electricity  Source of the texts:  Source of images and photos: https://images.google.com/https://images.google.com/

9  The energy from the sun can be converted into heat and electricity. Sunlight can be captured using photovoltaic cells which convert the sun’s energy into electricity  Source of the texts:  Source of images and photos: https://images.google.com/https://images.google.com/

10  Renewables are great because they don’t pollute and they provide energy from free, abundant resources.  Currently only hydropower is widely used as an energy resource, while the other four types of renewable energy are not commonly used as primary energy sources.  Reasons for their restricted use include the cost of specialty materials (e.g. photovoltaic panels are expensive to produce) and the fact that it can be difficult to distribute the power they generate.  Source: n%20Plans/RenewableEnergyLessonPlan.pdf
