Introduction

All of us use energy every day — for transportation, cooking, heating and cooling rooms, manufacturing, lighting, and entertainment. The choices we make about how we use energy — turning machines off when we’renot using them or choosing to buy energy efficient appliances — impact our environment and our lives.
The terms energy conservation and energy efficiency have two distinct definitions. There are many things we can do to use less energy (conservation) and use it more wisely (efficiency).
The United States is a highly developed and industrialized society. They use a lot of energy in our homes, inbusinesses, in industry, and for personal travel and transporting goods.
It almost always takes less energy to make a product from recycled materials than it does to make it from new materials. Using recycled aluminum scrap to make new aluminum cans, for example, uses 95% less energy than making aluminum cans from bauxite ore, the raw material used to make aluminum.
In the case of paper,recycling saves trees and water. Making a ton of paper from recycled paper saves up to 17 trees and uses 50% less water.
Information
-How we use energy:
We use energy to do work. Energy lights our cities. Energy powers our cars, trains, planes and rockets. Energy warms our homes, cooks our food, plays our music, gives us pictures on television. Energy powers machinery in factories and tractors on afarm.
-Energy & the environment:
Energy and environment are essential for sustainable development. The poor are disproportionately affected by environmental degradation and lack of access to clean, affordable energy services. These issues are also global as climate change; countries acting alone cannot address loss of biodiversity and ozone layer depletion. UNDP helps countries strengthentheir capacity to address these challenges at global, national and community levels, seeking out and sharing best practices, providing innovative policy advice and linking partners through pilot projects that help poor people build sustainable livelihoods.
-Saving energy:
Most of the energy we use today comes from coal, oil, and natural gas. They are fossil fuels. They take millions of years toform. We can’t make more quickly. They are nonrenewable. We need to save energy whenever we can. You can help.
Reduce
A good way to save energy is by not wasting things. Don’t use paper plates or cups all the time. You only use them once—then throw them away. Write on both sides of your paper. Use a lunch box and thermos instead of paper bags and box drinks.
Buy a small can of frozen juice to makeat home instead of buying a large carton that you have to throw away. Buy one big bag of chips—not ten little ones. Reducing waste saves energy. It takes energy to make things and to get rid of them. Buy things without a lot of packaging. Some candy has more plastic around it than food in it. What a waste!
Reuse
Try to use things more than once—reuse them. Wash out plastic sandwich bags and usethem again. Use the comics from newspapers to wrap presents. Buy toys at yard sales and you can save energy and money, too.
Paint your big sister’s old bike instead of buying a new one. Fix old things whenever you can. Give your old clothes and toys to someone who needs them—don’t throw them away.
Recycle
You can recycle lots of things—cans, paper, glass, and plastic. It only takes a minute torecycle, and it saves energy. It takes a lot of energy to dig up metal and make a can. It only takes a little energy to make a new can from an old one. Cans can be recycled over and over again.
Plastic bottles can be recycled into clothes and rugs. Paper can be recycled into boxes and bags. Don’t throw away anything you can recycle.

Save Electricity
You use a lot of electricity every day....
