Solar Energy is passive, delivered to your doorstep without a truck or power line. Solar Energy can reduce our need for electricity by beating water and air in our homes. Solar thermal energy-heat-can generates power when sunshine is concentrated at places. So the sun can offer our homes both heat and electricity. Here are some ways the sun’s energy can work in our homes:
Light rooms with sunlight
Preheat water for showers, baths, and laundry
Preheat air to maintain comfortable room temperatures
Provide electricity to power appliances and tools.

Renewable energy uses energy sources that are continually replenished by nature – the sun, wind, water, thermal heat, and plants. They’ve been here since the world began. Renewable energy technologies turn these fuels into usable forms of energy – electricity, heat, mechanical power, and chemicals. Below is the flowchart of Renewable Energy Power System.

Life is good. Electricity keeps our food cold or warms it up, washes the dishes, and entertains us while we eat. It also runs our computer, washer, lights and garage-door opener. But there is a cost which we need to pay for it – the electric bill. However, is that all we’re paying? No, it’s not. There’s another bill – an energy-use bill that we pay every day in the form of spent resources that we can’t get back, smog and health problems, taxes for energy regulations, wars, and other concerns. These costs total into the billions of dollars. We get the other bill in increased health costs, higher consumer costs, and higher taxes. So what can we do? We can look to alternative energy sources, especially those such as the sun, that minimize long-term bills. Maybe we can’t change the whole world, but we can change our little piece of it. We can consider solar and other renewable energy sources to power our homes.
