Renewable Energy

The energy which replenishes itself quickly and which is available in never ending supply is called alternative or renewable energy. The renewable energy comes from natural resources like sun, wind, water (tides and rainwater), heat from the earth (geothermal heat), biomass etc. There is no end to the renewable sources of energy on earth. As long as human life is there, there will be earth, sun, wind and water, and the energy from these sources will also be available as long as they are there.

1) Solar energy from sun: This is one of the most commonly used renewable sources of energy. Solar energy is being currently tapped for food cooking, water heating, electricity generation, lights, etc. The solar collectors are installed that collect the solar energy and convert it into various forms.

2) Wind energy: Wind energy is being used extensively for generation of electricity. Huge fans are installed to tap the wind energy and convert it into electricity for domestic as well as commercial applications. It is popular in countries like India, China, US, Denmark, etc.

3) Geothermal energy: The heat from the earth is called geothermal energy. It can be used to heat water, generate electricity, etc.

4) Biomass energy: This is the energy stored in the organic matter generated by the plants and animals.

5) Water energy: The energy obtained from tidal waves, rain water, etc. is the renewable energy obtained from water.

7.Indoor Environmental Quality: How to Avoid Indoor Pollution.

Air is a mixture of gases, mainly nitrogen and oxygen, usually contains some Water Vapour

and like other gases had own characteristik, to be axact: Volume Temperature Weigh Pressure

Enviromental quality be devisible by indoor and outdoor. Air be included in indoor Enviromental quality.

"Indoor Environmental Quality," as the name implies, simply refers to the quality of the air in an office or other building environments. Trough of poor quality aeration and indoor contaminants can be develop respiratory symptoms or allergic reactions. Indoor environments are highly complex and building occupants may be exposed to a variety of contaminants (in the form of gases and particles) from office machines, cleaning products, construction activities, carpets and furnishings, perfumes, cigarette smoke, water-damaged building materials, microbial growth (fungal/mold and bacterial), insects, and outdoor pollutants.

Here are five things you can do to get rid of air indoor pollution.

1. Keep your floors clean. Floors tend to accumulate much of the dust that can rise into the air and present a threat of respiratory problems.

2. Do a radon test. If radon level higher than norm, it can be develop cancerous illness....

3. Don’t smoke indoors.

4. Dehumidify. Appropriate humidity in your home around 30-50%.

5. Use natural products
