Save Energy Essay, Research Paper
Energy is one of the most fundamental parts of our universe.
We use energy to do work. Energy lights our cities. Energy powers our vehicles, trains, planes and rockets. Energy warms our homes, cooks our food, plays our music, gives us pictures on television. Energy powers machinery in factories.
Energy is defined as “the ability to do work.”
When we eat, our bodies transform the food into energy to do work. When we run or walk,
we “burn” food energy in our bodies. When we think or read or write, we are also doing work.
Cars, planes, trollies, boats and machinery also transform energy into work.
Work means moving something, lifting something, warming something, lighting something. All these are a few of the various types of work. But where does energy come from.
There are many sources of energy. In this guide, we will be looking at the energy that makes our world work. Energy is an important part of our daily lives.
The forms of energy we will look at include:
+ Geothermal Energy
+ Fossil Fuels — Coal, Oil and Natural Gas
+ Hydro Power and Ocean Energy
+ Nuclear Energy
+ Solar Energy
+ Wind Energy
We will also look at turbines and generators, at what electricity is, how energy is sent to users, and how we can decrease the energy we use.
Some of the energy we can use is called renewable energy. These include solar, wind, geothermal and hydro. These types of energy are constantly being renewed or restored.
But many of the other forms of energy we use in our homes and cars are not being replenished. Fossil fuels took millions of years to create. They cannot be made over night.
And there are finite or limited amounts of these non-renewable energy sources. That means they cannot be renewed or replenished. Once they are gone they cannot be used again. So, we must all do our part in saving as much energy as we can.
In your home, you can save energy by turning off appliances, TVs and radios that are not being used, watched or listened to.
You can turn off lights when no one is in the room.
By putting insulation in walls and attics, we can reduce the amount of energy it takes to heat or cool our homes.
Insulating a home is like putting on a sweater or jacket when we’re cold…instead of turning up the heat.
The outer layers trap the heat inside, keeping it nice and warm.
To make all of our newspapers, aluminum cans, plastic bottles and other goods takes lots of energy.
Recycling these items — grinding them up and reusing the material again — uses less energy than it takes to make them from brand new, raw material.
So, we must all recycle as much as we can.
We can also save energy in our cars and trucks.
Make sure the tires are properly inflated.
A car that is tuned up, has clean air and oil filters, and is running right will use less gasoline.
Don’t over-load a car. For every extra 100 pounds, you cut your mileage by one mile per gallon.
When your parents buy a new car, tell them to compare the fuel efficiency of different models and buy a car that gets higher miles per gallon.
You can also save energy in your school.
Each week you can choose an energy monitor who will make sure energy is being used properly.
The energy monitor will turn off the lights during recess and after class.
You can make “Turn It Off” signs for hanging above the light switches to remind yourself.
You can start an Energy Patrol in your school. Click the words Energy Patrol to go to another location in our Internet site that tells you how to set one up in your school.
You can make sure your classmates recycle all aluminum cans and plastic bottles, and make sure the library is recycling the newspapers and the school is recycling its paper.
Conclusion
To make sure we have plenty of energy in the future, it’s up to all of us to use energy wisely.
We must all conserve energy and use it efficiently. It also up to those of you who will want to create the new energy technologies of the future.
One of you might be another Albert Einstein and find a new source of energy. It’s up to all of us. The future is ours but we need energy to get there.

Compared to fossil fuels, sunlight is a weak energy source.
Compared to fossil fuels, sunlight is a weak energy source
Capturing sunlight is not as easy as it sounds. It is a dilute energy source, spread out over time and space. Earth receives 5.6 x 1018 (5,600,000,000,000,000,000) megajoules of solar radiation each year (Box 1), but to make it worthwhile we need to collect it over many hours and across many square metres of ground. We then need to concentrate it so as to make available the sort of power that modern society needs. Sunlight is not as energy-dense as oil but this is made up for by the fact that it is present over such a large area.
By careful design and positioning of houses we can use sunlight to warm our homes and our domestic water. This passive solar heating can help us reduce fossil fuel use (and save money) but it s n
Наверняка у вас есть товары или услуги, продажа которых приносит вам максимальную прибыль.
