The world has seen the discoveries of some extremely incredible sources of energy. From the ancient men who learned the different ways to use fire, to the ambitious people of the 1800′s who realized that fuel and oil were not only excellent for lamps but for automobiles too. Now, we really have a fantastic variety of energy sources and it is up to us to choose which ones are best for our economy, our needs, and our world.  We all know that the presiding energy source today is oil; and we are all equally aware of the many challenges facing the oil industry.  Only months away from BP’s recent oil spill, we are even more aware of this industry’s undeniable consequences for our earth not to mention for our economic dependence on unknown powers.   But what other types of energy sources are unfilled and how can we use these alternative energy sources as a replacement for?  A few of these unfilled today include wind, hydro power, and solar energy.

Using wind when powering our homes and buildings does have its pro’s and con’s. According to the department of energy, it is estimated that wind power could account for twenty percent of the nation’s electrical supply by 2030.  Using wind power to provide electricity to cities is a fantastic thought when it comes to preserving oil and cheapening the cost of transporting it.  Two problems with wind energy include the inability for the turbines to be constantly spinning, and the fact that they often blow the toughest in deserted areas far away from the populations that need the energy.   Building such massive turbines often requires significant out-of-gauge cargo transportation to some of the most remote places on the earth, allowing gigantic facilities to be built and operated.  Finding more ways of efficiently getting wind energy to the cities that need it and compensating for the occasional lack of wind, will allow this energy source to be more useful and productive.

We’ve all seen the shows lobbying for solar power as a viable energy source. According to the New York Times, solar power accounts for less than one percent of United States electricity use. The majority of solar power use is found in the state of California. The type of solar power most often used is called concentrating solar power. By using mirrors, you can reflect the sun’s rays which yield enough heat to power a generator. Another way is by solar panels found on roofs which are called photovoltaic panels.  These panels are transported crosswise the country or crosswise the globe by cargo transportation specialists who can make sure proper transportation and storage space in order to build effecting solar capturing stations in key energy deficient locations.   The subsidy of using solar energy for power is that it is really safe for the environment. Unfortunately, solar panels tend to be very expensive and are obviously of no use all through the night.  According to the New York Times solar panels cost four times more than what coal expenditure and double the price of what it would cost you to use wind power. Although these are tough facts to gulp, this age is quickly advancing. Scientists are continually researching more efficient ways to use solar power for the subsidy of the American people.

The use of water as an energy source was introduced to the world before electricity had a name. You may remember the water propellers often seen on the side of homes while surveillance ancient country movies. Well that form of energy is still being used today, except, you should be thinking even larger than that. The United States Department of Energy described hydro power this way. “Water constantly moves through a vast global cycle, evaporating from lakes and oceans, forming clouds, precipitating as rain or snow, and then flowing back down to the ocean. The energy of this water cycle, which is driven by the sun, can be tapped to yield electricity or for mechanical tasks like grinding grain.”  A recent New York Times article confirmed that hydroelectric facilities supply 19 percent of all electricity crosswise the globe, and between 7 and 9 percent of electricity in the United States. 

Alternative energy is not only environmentally friendly but it is becoming more and more necessary both for the subsidy of our world and our economy.  All energy sources present challenges when harnessed, but the more we expand our horizons and promise, the more equipped we will be to face the future. The price and availability of these energy sources is improving daily, and the United States is working its’ way to developing a more eco-friendly environment for generations to come.

What Are The Matter-of-fact sources Of Energy? – Part 1

The matter-of-fact sources of energy include the fossil fuels, natural gas, petroleum (or oil), and coal. Fossil fuels are referred to as nonrenewable energy sources because, once used, they are gone. Scientists are exploring the practicality of other sources called renewable energy sources. These include sun, wind, geothermal, water, and biomass. The renewable energy resources are vital in long range energy plotting because they will not be depleted.

Natural Gas

Now and again natural gas is confused with gasoline, the fuel in cars. They are not the same. Gasoline is a mixture of liquids, and natural gas is mainly methane and is piped into homes and office buildings where it is used as an energy source for heating, cooking washing, and drying. It is raw material to make other chemicals, and is the cleanest bumming fossil fuel. This means it contributes small environmental pollutants when bummed.

Petroleum or Oil

This is the black, thick liquid pumped from below the earth’s surface wherever you see an oil rig. To make it useful, it is refined. Refining separates the gasoline part which is used in transportation. Products from the remaining parts include synthetic rubber, detergents, fertilizers, textiles, paints, and pharmaceuticals.

Geothermal

Geothermal energy refers to the energy deep within the earth. It shows itself in the fountains of boiling water and steam known as geysers. Geothermal energy was generated by the decay of natural radioactive equipment within the earth. In addition it is the heat energy remaining within the earth from gravitational formation of the earth. This energy source is not well loved in the United States, but Yellowstone has some geysers. Geothermal energy is used to heat some homes, greenhouses, and factories. The actual usable geothermal sites are few, but is considered a renewable energy source.

Coal

Coal is the most abundant fossil fuel. It is not a widely used energy source due to the cost of mining and its impurities, which cause pollution (acid rain). There are two ways to mine coal; underground mining and strip mining. Drawback to these methods is the environmental change caused in the process. New ways of using coal are being explored, such as liquefication, in which a product similar to oil is produced.

Solar

The sun is 93 million miles away and yet, this ball of hot gases is the primary source of all energy on earth. In the hi ugh temperature of the sun, small atoms of hydrogen are combined, that is, the centers of the two atoms are combined. Fusion releases far greater energy than splitting the atom (fission, see below). Without sunlight, fossil fuels could never have existed. The sun is the supplier of energy which runs the water cycle. The uneven heating of the earth produces wind energy. Solar energy can be used to cook food, heat water and generate electricity. It remains the cleanest energy

source an it is renewable. It is the hope for the energy source of the future and scientists at NREL are actively working on ways for solar energy to supply more our energy needs!

Years ago, no one ever thought that solar powered vehicles are even possible. There are solar-powered calculators or solar batteries that can run small devices but as for solar-powered car engines, many have remained skeptical until they finally saw actual vehicles that run on the energy of the sun made for exhibits in various science and technology fairs. These days, many are already considering on the possibility that, in the next couple of years, mass-promote solar powered vehicles will be unfilled to consumers in replacement for the ones that run on oil fuel.

These days, one can see solar powered vehicles in engineering demonstrations and solar car race events.

Cost-efficient

Solar-powered vehicles are, without a doubt, more cost-efficient than the typical cars that run on oil fuel. After all, these cars harness energy from something that is abundant ‘ the energy from the sun. So long as the sun shines, these cars should be able to run just as efficiently as any other type of vehicle. Because they run on solar power, these vehicles will also delight in privileged mileage and longer life spans according to most experts. Solar powered vehicles offer a lot of benefits to the potential consumers who would be keen to invest on such cars.

While solar powered vehicles are not yet matter-of-fact day-to-day transportation devices, it’s only a matter of time before they really get introduced into the promote.

How they work

Solar powered vehicles literally run on the energy coming from the sun. They follow the same thought as that of other solar-powered devices such as calculators or batteries. The surface of the car has solar panels that collect solar energy. Photovoltaic cells installed in the vehicle work to convert this energy into electrical energy that the engine will need to run the car. In theory, solar powered vehicles will only run when the sun is present. But, numerous studies are now being conducted with regards to the creation of energy trapping components that will enable the car to store enough energy for it to run even at night.

Design

The design of solar powered vehicles is largely limited by solar batteries that are installed in it. Most cars that run on the sun’s energy are designed to be lightweight. Every component shouldn’t weigh as much as the ones that you would typically find in conventional cars. They do have practically the same basic parts that traditional vehicles have. You will find brakes and accelerators in them. Some even come with cruise control.

Challenges

With solar powered vehicles, the contemporary challenge is to make a process or a mechanism that is competent of harnessing solar energy efficiently even on places with a relatively smaller surface area such as cars roofs. Solar cells are usually effective on buildings because they are always exposed to the sun’s heat. Cars will warrant more attention on this area to make efficient solar powered vehicles that can be used just like cars that run on oil fuel.
