Solar Renewable Resources

Cooking

• Because solar energy creates heat, it can be used to cook foods using a solar cooker. Solar cookers are generally made up of reflectors that concentrate sunlight in a certain spot, raising the heat level enough to cook food. It can take longer to cook certain types of foods and can be compared to the low and slow method used by slow cookers. The food is also difficult to burn.

Electricity

• The energy of the sun can be used to create enough electricity to make a difference in a home electricity bill. The energy from the sun is captured by a solar cell and transformed into electricity. In a sunny climate, 1 square meter of solar panel can power a 100-watt light bulb. Solar electricity has been developed to the extent that many calculators are powered by small solar cells.

Heating

• Solar heaters capture the heat from the sun and use it to heat spaces or water. Solar water heaters run water through tubes that are exposed to the sun, absorbing heat. The water can then be used in the house to wash dishes or take a shower. Most systems are installed on the roof, but some systems are more compact and feature many tubes lined up together.

Home Construction

• Methods of home construction can maximize the use of solar energy in the home. Passive solar construction is designed to create a comfortable home without using much or any other energy. The home is oriented depending on the position of the sun to maximize the amount of energy the house picks up for use as heat or electricity. Homes located in warm areas use energy provided by the sun to cool the house and have features that keep sunlight out to prevent heat buildup. Homes located in cooler areas use the energy from the sun to heat the house and have more windows to allow more heat to enter the house.
