Created with Fabric.js 1.4.5 The other way is solar thermal.Solar thermal: solar energy is used directly to generate heat. Solar panels are used to trap the heat from the sun and are used to heat water in the glass panels. Glass panels are painted black so that they absorb maximum energy from the sun, then water is pumped through these pipes. These panels are positioned in such a way to maximize the absorption of heat through out the day and can help in reducing the electricity bills. Environmental issues: The environmental issues are technological limitations, and socio-economic factors. Renewable/ Non-renewable: Solar energy (sunlight) is a renewable energy (source). Process of energy production: There are two ways to produce solar energy either solar thermal or solar photovoltaic.Solar photovoltaic: photovoltaic cell is the solar cell, which captures energy from the sun and converts it into electrical energy. In a solar cell, sunlight shining on the cell creates a flow of electrons because the materials in a solar cell can convert sunlight into electrical energy. Since the sun radiates light every day, sunlight is a renewable energy source. Definition: Solar energy is an energy provided by the sun.This energy is in the form of solar radiation, which makes the production of solar electricity possible. Electricity can be produced directly from photovoltage. Solar Energy What percentage of Ontario energy is being produced this way?24% of Ontario's energy were produced this way. Advantages: Don't produce air or water pollution. They can operate independently of power grid or be connected to it. These systems are also maintenance-free when they are properly installed, and can last more than 40 years. Disadvantages: Solar panels are only about 30% efficient at converting sunlight into electricity because of the limitations of the materials used to make the panels. The cost of solar panels can be expensive. Solar panels don't produce large amounts of electricity immediately. Instead, each solar cell needs several hours of sunlight in order to produce a significant amount of electricity. Interesting facts: As our electrical requirements increase, governments and citizens need to make choices on how to best meet that demand. These choices involve developing better and more efficient ways to generate electrical energy while also considering the source and effects of its use on the environment. Another important consideration is to develop ways to use less electrical energy. Resources: Science textbook page 527, Websites:, and www, Where in Canada is this being used? Why? Solar energy is used at any sunny location. In the manufacture of solar panels and in the disposal of broken solar panels.
