energy saving ways

. Modern homes are built to conserve fuel by using building materials and methods that insulate the house. In the colder parts of the world insulation helps to keep heat in and save fuel. Relying more heavily on renewable resources and recycling of wastes into energy can help to..

Nuclear Energy and Chemical Energy - Nuclear energy is released when very small particles of matter split or combine. After the split or combination, they result in small particles or heavy particle. The rest of the mass is changed into energy. This process o..

Wind Energy - Wind energy is one of the first sources of energy known to man. The sun's rays are stronger nearer the equator than in the polar region. This heats the air in equatorial region and warm lighter air rises while cooler polar air moves in to replace it. This..

Wind energy is one of the first sources of energy known to man. The sun's rays are stronger nearer the equator than in the polar region. This heats the air in equatorial region and warm lighter air rises while cooler polar air moves in to replace it. This movement of air results..

. Rainwater, which seeps into the ground and slowly percolates down through cracks in the upper crust, also gets heated by the hot rock beneath. In certain areas below the earth's surface, hot magma swells up into the crust, but remains trapped below the surface of the earth. Such areas in the eart..

Internal Energy - Internal energy is one of the most important concepts in thermodynamics. Energy changes in a body sliding with friction. Warming a body increases its internal energy and cooling the body decreases its internal energy. However, what..

The heat and light energy emitted by the sun's radiation is called solar energy. Earth receives about 640 J of energy per second per square metre from the sun. The Sun's energy has two aspects. The 'heating effect' of sunlight, which is due to the infrared r..

Water, being a vital resource for all living beings, is also an important source of energy. Hydropower supplies 6% of the world's energy needs. Moving water is highly energized. A hand held into a fast flowing stream can feel the pressure of water trying to push the hand along. ..

R is the internal energy of the reactants. If the internal energy of the products is less than the internal energy of the reactants, the D E would be negative. On the other hand, when the internal energy of the products is more than the internal energ..

Science is a Way of Life - Science is the hallmark of progress in the realm of naturally occurring matter and energy. It is the way one has to get at the truth or at least, as close to the truth as possible. WHAT is Science? * Science is a human endeavour * Science is ..
