Renewable energy, also known as alternative energy includes many technologies such as wind energy, solar hot water and space heating, fuel cells, bio fuels, hydro power and photovoltaics (solar panels that turn light into electricity). According to International Solar Energy Society (ISES) photovoltaic power generation grew by 73% in 2008 making it the most popular method to generate renewable energy.
Why do you think using solar panels to generate electricity is more popular than other renewable energy technologies? Why is photovoltaics is more practical for homes and businesses to use than other renewable energy technologies? What are the factors that have increased the use of photovoltaics compared to wind power?
