Nuclear plants can stimulate the US economy.


"Nuclear plants are the most capital-intensive investments made in the utility sector, and they produce millions of times more power in terms of energy flux density than any other power source. "(Marsha Freeman, 2009, p. 42)
Nuclear energy is the good way to overcome the crisis. Nowadays 104 nuclear plants are inside the US, including 28 new plants. Nuclear energy is a very important resource for the USA, but furthermore, it is very dangerous. One nuclear plant can produce 600 millions megawatt energy hourly, but misoperation of nuclear system can destroy everything, how it was in Chernobyl. Here there was Chernobyl Atomic Power Station where in April of 1986 the reactor blew up. It was dreadful accident.
The nuclear energy is used by people in the future projects, for instance, fuel for a space vehicle. After a thirty-year break, the US government resumed the construction of nuclear plants to stabilize the economy and get more energy. It is obvious that the government don't forget about the protection of nature, because nuclear plants are one of the most environmentally unfriendly thing. Millions of dollars are spent on the developing of new ecological reactors for plants.
If the scientists develop nuclear technology, The USA will not have lack of energy.

Solar Power will make a difference.


Humanity tries to develop new types of energy, for example, wind, solar, or hydrogen energy. In this post I would like to tell about developing of solar energy. A lot of energy resources are limited. As for solar energy, Earth can get limitless solar power from the sun and people use this opportunity. We use solar power to "produce electricity without releasing any
greenhouse gases."(Cass, Stephen,Sep/Oct2009, p93) Europeans have already installed a solar roof to get electricity from the sun; but this way of getting electricity is not cheap. The scientists explore new and cheap ways to get solar power: silicon based photovoltaics. We will use these technologies only in future. Besides, in future humanity will be able to use solar cells out of organic polymers and harnessing solar energy to split water into oxygen and hydrogen will appear. It will be nano-technologies which change our world. If the USA explore these technologies, Americans can forget about the electricity problems.

My opinion. What kind of energy is the best?


There are a lot of kinds of energy in the world: solar, electrical, mechanical, and wind. It is very hard to understand what type of energy is the best. I think, wind energy is the best one. This type of energy is the safest one; it is also ecologically clean. It has a lot of advantages,for example,it is a great source of energy generation. But it has some disadvantages: problems when there is zero wind, and high price of generator. Such countries as China, the USA, European countries, Japan, Russia, and some countries of South America use wind energy. I think that scientists will develop this type of energy and in the future we will be able to see more developed wind generators.
This is good video about wind energy: http://www.youtube.com/watch?v=LQxp6QTjgJg

Energy in the future.


Nowadays scientists are looking for the new sources of energy that will replace gasoline, oil, and natural gas. It will be a new period in energy developing. Energy will become more strong and ecologically clean. Alternative energy is our FUTURE.
There is a scientific definition of alternative energy: "Alternative energy is an umbrella term that refers to any source of usable energy intended to replace fuel sources without the undesired consequences of the replaced fuels." It is a very difficult definition; in other words, it is just a replacement of current energy.
There are some concepts of alternative energy: Floating wind farms, biogas digestion, biomass briquettes, helioculture (removes carbon dioxide from the air as a feedstock for the fuel) and biological hydrogen production. Wind is a source of ecological energy for future. Other types of alternative energy are developing in chemistry. Synthesizing of some types of fuel results in appearance of the energy of future. Essentially, the alternative energy will be used in transportation: the planes, cars, ships or space vehicles. Perhaps, alternative energy will make our life better, but we should not forget about rational usage of future energy.

How you can save energy.


We cannot live without energy. Energy is everywhere; but imagine that some day energy will disappear. It will be chaos. Therefore we should begin to save energy right now. There are a lot of ways to save energy.
1. Turn off the lights and all electronics when we don't use it.
2. Use microwave instead of the oven.
3. Set your home’s thermostat a few degrees lower
4. Use washing machine, dryer... after 8 p.m.
5. Different energy programs can help you to use energy more effective.
Some of these ways can help you to save not only energy but also money. Our world is being destroyed now and each family can save it.

Energy in Russia



Russia is a big country with vast area for developing of energy. Energy plays a very important role in Russian economy and economic sectors: in the industrial, agricultural, commercial, and government sectors.
Natural gas holds a central place in the economy of Russia. Russia has 49 billion cubic meters of gas. It is 35 percent of the world's total. IT is an essential resource for exchange. It brings essential income to the Russian treasury. Therefore the gas companies are the richest.
oil holds the second place. Russia ranks the third place on the petroleum reserves after The USA and Saudi Arabia. Approximately, our country has 8-10 billion tons of oil.
Coal is too very important recourse for Russia. This recourse is very hard to get. In the past years, coal was the basic fuel for Russian industry. Nowadays Russia has about 200 billion tons of coal.
These energy resources help our country survive, and Russian government spend a lot of money on exploring this energy.

Life without energy.


You are in the place full of darkness. You can not work, cook or do anything else. This is Chaos. This is life without energy.
We can not live without energy. The electricity give the life for us. We even don't think that some people live without electricity and that it is possible. There are 1.5 billion people in the world who don't have access to electricity. Generally, such people live in Africa. This is a very big problem of humanity. It destroys life of poor people. Without energy people can't get energy, they don't have good conditions for life, people can't raise a family. As for health, it may be good to live without energy. But people die without energy and this situation go worse from year to year. People should find a solution to save billions of people.
"This is the stark reality for billions of poor people."
