Electric Energy And Power

Electric Energy's Brief History

Some Common Examples Of How Mechanical Energy Is Used

Mechanical energy is the energy contained in an object due to the motion of the object or because of its stored energy of position. It can take the form of kinetic energy also known as energy of motion, or potential energy, which is stored energy of position. When an object moves, it is said to have mechanical energy, and also if it is at some position relative to a zero potential energy position.

Clean and Free with Wind Energy

One of the oldest forms of used energy in the world, wind energy is now one of the many alternative forms of energy being looked at to wean many countries off of their oil dependency. It's perfectly clean, totally free, and it's now being used to empower a large percentage of a country's energy needs in many cases. This type of energy does have a bit of science behind it though, so we'll take a look at what makes wind energy work and where it's being used right now.

Thermal Energy: No Clear Definition Of What It Is

Thermal energy has no known definition and the term cannot be really found in a dictionary of physics or science. Mostly, it is thought of as being a synonym for thermodynamic energy or a synonym for heat. It can however, have two components which are internal potential energy as well as internal kinetic energy.

US Department Of Energy Needs To Convince America To Go Solar

One of the main goals of the US Department of Energy is to show the way by finding adequate solutions by which to reduce the country's dependence on fossil fuel and to also do something fast with regard to pollution in the United States. Acting with the intention of achieving its objectives, the US Department of Energy has come up with a novel solution in the form of the Million Solar Roof Initiative.

Flat-Screen TVs Threaten Energy Saving Efforts

Efforts to reduce the amount of energy we use in our homes are being threatened by the growing popularity of gadgets such as flat-screen plasma and LCD TVs. A study by the Energy Saving Trust found that UK consumers spend around £12bn a year on electronics, much of which is less efficient than older technology.

Blair Says Nuclear Power is Needed

The British Prime Minister Tony Blair has said that nuclear power is needed to help reduce carbon emissions and to ensure secure energy supplies. The prime minister's words came as the Energy White Paper was published, proposing a large increase in renewable energy.

Light Energy Offers Viable Source Of Power

There is a very close relationship between light and energy, although many never think much about it until it is dark. It is the light energy from the sun that provides life to most things on the Earth and learning to harness that energy can help provide renewable energy resources. Light travels at the speed of about 186,000 miles per second and simply traveling through space the light energy from the sun arrives on the planet about eight seconds after it leaves the sun.

Stream Energy And Deregulation

Since the start of 2002, the state of Texas has been operating its electrical utilities under a mandate by the state legislature to deregulate the electricity market and enable most residents to choose the company that will supple their energy. The reasoning behind the mandate is to allow a free competitive market to set prices and levels of service instead of relying on electrical monopolies. Under the law, minimum prices were set for the established companies to create a level playing field. New companies were permitted to charge lower prices in order to compete and build a business base. Since the deregulation began, the previously established monopolies have been able to maintain their hold on 70% of the market. A few new companies have emerged, however, including Stream Energy.

The Benefits Of Hydroelectric Energy

To generate electricity, a form of energy has to be changed to another type of energy and the result has to be stored in a form that can be transmitted. Most power plants take stored energy in the form of coal or natural gas and transform it with fire to produce electricity.

Movement Made Possible by Kinetic Energy

Most people have a vague idea of what energy is. They might believe it to be a sort of fuel that allows objects to move and work. While this is true, energy is a much broader set of theories and laws that helps define our universe. For example, chemical energy contains the energy that helps bind atoms together in chemical bonds. Mechanical energy is energy transferred by a force, such as when two objects collide. To be capable of moving, objects need to have kinetic energy.

Some Energy Sources

In a society that is dependent on increasing amounts of energy, the experts and scientists that we rely on are turning to studying the pros and cons of various energy sources. All energy sources are the materials or the processes that contain concentrations of energy or potential energy.

Making Things Work with Mechanical Energy

Many types of energy exist throughout the universe which help hold matter together. Chemical energy allows atoms to bond together. Kinetic energy allows objects to accelerate and decelerate. But how do you explain hitting a baseball with a bat and watching the ball fly in the opposite direction? Mechanical energy allows the transfer of energy from one object to another.

Renewable Energy

It might seem like the end of the world is near when it comes to energy. Everywhere people are saying that we are running out of fossil fuels and that we are depleting our resources quickly. It doesn't seem like there is much energy left in the world, but that is simply not true. The key is to find sources of energy that are renewable, which means that once you use it, it isn't gone forever.

Electromagnetic Energy Can Harness Sun's Possibilities

Energy from the sun travels to the Earth in various wave lengths, including ultraviolet, from which sunburns and suntans come from, as well as the visible light spectrum. Included in the sun's waves is the electromagnetic energy waves that can be converted to electricity through photovoltaic cells. For standard uses, electromagnetic energy is the convergence of electric waves and magnetic energy applied at right angles. Different wavelengths create different uses for the energy, one of which is in the use of electric furnaces for melting metals in industry.

Radiant Energy: Is It As Harmful As It Sounds?

Radiant energy is something that has always been mistaken for being harmful, for generally people think that it refers to energy produced from radiation. Radiation in that definition is somehow correct, but it's not in the same sense. Radiant energy here is the one in electromagnetic waves, which we use daily for so many purposes in life.

The Time For Conservation Of Energy Is Before It Is Gone

It has been said for the past 30 or more years that the conservation of energy is a must if the world is to avoid an energy crisis. There is only so much coal, oil and natural gas hidden in the planet and once it has been used up, there will be no more. Research has shown that it took millions of years for these fossil fuels to form inside the planet and unless steps are taken for the conservation of energy before the supply is depleted, there will be a shortage of available power.

Deregulation and Atmos Energy

The way that energy for home and business is being developed and marketed is in a state of change. The lessons learned from the many experiments in that area will have a huge effect on the way that energy is distributed in the future - and the prices that will be charged.

Everything Has Energy

Refining The Use Of Renewable Energy Sources

There is continuing research on ways to use renewable energy sources as the threat of depleting non-renewable materials becomes more serious. For many years, the use of fossil fuels has been the driving force behind the production of energy, but as the world's supply of oil, gas a coal starts to near its end, as well as the polluting effects becoming more apparent, the drive for cleaner and renewable energy sources heads into high gear.

Three Different Devices That Can Be Used To Capture Wave Energy

The fact is that with over seventy percent of the surface of our planet covered by oceans, there is a ready source available for creating energy without polluting the environment and at an affordable cost as well. No doubt, ocean activity is generally affected by the sun though tides are primarily driven by gravity and more particularly the gravity from the moon, while waves are affected by winds. Also, waves are created by the wind on the sea's surface, and so, these waves can be used as potential source of renewable energy.

Increase Your Home's Energy efficiency

With energy shortages and global climate change in the headlines, more and more homeowners and renters want to know how they can increase their home's energy efficiency. Whether you own your home or rent, almost every resident can do something to improve the energy efficiency of their dwelling.

Why Renewable Energy Is So Important

In today's society, we use gasoline to power our cars and boats and planes and that gasoline is made from oil. However, the more oil we use to power the things we need, the less of it there becomes. That's because oil and coal, and other Earth resources that must be mined in order to be utilized for electricity and power, are in limited supply. The more we use, the less we have and one day we will run out. That's why more people than ever today are trying to push for our government and our society to adopt renewable energy as the energy source of the future.
