Energy Conservation A Major Part of the Solution to Energy Generation and Global Warming Dennis Silverman U. C. Irvine Physics and Astronomy Why Us (U.S.)? With 5% of the world’s population‚ the U.S. uses 26% of the world’s energy. A U.S. resident consumes 12‚000 kWh of electricity a year‚ nine times the world’s avg. The average American household emits 23‚000 pounds of CO2 annually. Two billion people in the world do not have electricity. Just using off the shelf

Water Conservation Water is essential to Earth. We need it to cook‚ bathe‚ provide power‚ control fire‚ and last but not least‚ we need it to live! Therefore‚ it is very important to human survival. When 70% of Earth is made up of water‚ you would think that we have plenty of water for our needs. But really‚ about 97% of that water is made up of ocean. We cannot use this water because it is too saline for our needs. Only 3% of Earth’s water is fresh‚ and 2% of that supply is frozen

Lab: Momentum Conservation Abstract This experiment aims to test the law of conservation of momentum by using cart and track system. Procedure 1. Put two carts onto the track. 2. Hit the button on the cart so that they start to move at opposite directions. 3. Find the position where the carts hit the end at the same time. 4. Find the distance that each cart traveled. 5. Repeat step 1-4 with 500g and 1000g weights on one of the carts. Data and Calculation m1m2=x2x1

Abstract Energy management and conservation is an important tool to help enterprises to meet their critical objectives of short term and long term goals. The main objective of the energy conservation is to maximize the profit‚ minimize the cost of energy and to ensure sustainability in the long term. India is one of the largest tea producers in the world‚ with an annual production of more than 856‚000 tons. Estimates indicate that 1.3 million tons of firewood and 435 million units of electricity

Water Conservation Water conservation is important because we depend on it. So many of our daily activities‚ like bathing or flushing the toilet‚ require fresh water. Our body even needs water to function correctly. Seventy-one percent of the Earth’s surface is made up of water. Ninety-eight percent of it all is salt water‚ leaving only two percent as fresh water. More than half of the fresh water is permanently frozen in glaciers or is in the form of snow. That leaves just a tiny
