wind gusts generate up to 233 megawatts of power every minute (Roberts 12). Homeowners and farmers can now own their own wind turbines and have their unused energy purchased by energy companies. Wind energy is very popular in Germany especially where at least 33% of the countries energy comes completely from wind turbines (Roberts 13). The sun radiates vast amount of energy, which nourishes all life on earth and is the driving force behind the planets weather patterns and other natural cycles. In order to take advantage of this vast and continuous energy supply, we learned to convert solar energy into forms of energy that we can use for heating and transportation. Solar energy systems developed for buildings can help meet the energy needs of the people who live or work in them in many ways. Such systems are often described as either passive or active. Passive system relies on the design and materials of the building to distribute light and heat from the sun without mechanical help. Active systems use pumps or fans. For example, it is used for water heater system, electricity supply and any others. Wind energy, for example windmills, have been used for hundreds of years to grind grain and pump water. More recently, they have powered small electric generators. Researchers are

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
