Is Alternative Energy The New Eldorado?

There is money in alternative energy and big corporations are discovering this fact. Not only are existing companies securing their position, new companies that specialize in this new energy source are increasing also. Is there really money to be made or is this the new Eldorado? Many believe that this new form of converting ‘free’ energy has real potential. Let’s look at the most important reasons why.

The energy sources we use today have negative side effects. They cause lots of pollution. The pollution causes acid rain and the earth warm up. Besides these side effects the current reserves are diminishing. The crude oil reserves will last for the next 45 years to come and gas maybe 60 years. The only traditional fuels source that is still in ‘abundance’ is coal. The coal supply will last for the next 300 years. Thus, for everything that runs on a form of crude oil or natural gas we will have to find a good replacement. Many of us think alternative energy is the answer.

Why is alternative energy the answer for our energy problems? There are several reasons why. First it is a clean form of energy that doesn’t cause any harmful effects to the environment. We are realizing that this beautiful planet we live and breathe on needs to cherished. Not only for us but more important for our children. Thus we need to live our lives in a way that is not harmful for our planet. We are doing it right now and need to change that. Alternative energy can be the answer.
Second, these ‘new’ energy sources are available for nearly every one and they are ‘free’. Energy sources like the wind, sunshine and water are for every body and are free to use. We need technology to convert these sources in to useful energy needed for our appliances and transportation. These technologies come with a price tag and one can argue if these investments are worth it. If you feel that the investments are worth it or not, the technology is available. For the individual and for companies there are amazing technologies on the market. Companies that specialize in these energy sources are improving and coming up with new concepts that are better than ever before.

Companies that are developing these technologies are investing in their and our future and can become the next ‘oil barons’. They are not only securing a clean planet, but are also making money. History has taught us that technology is the key for success in the western modern world we live in. These companies that develop these new technologies can sell their knowledge through appliances and services they offer. Consumers and other needing companies are willing to pay for this. You can ask yourself if it is wrong that these companies are making money on something that is ‘free’ for all. When you really think of it, it really is nothing more than what is happening today all around us. It is just plain and simple economy, some one offers a product and another person buys that in exchange for money. Of course the price must be right.

When it comes to making use of alternative energy we need technology to convert the ‘free’ energy sources into forms that we can use. This technology can be expensive, but you will be saving money also. Because many governments are endorsing it, you may profit from tax credits as well or other benefits. Thus, for the right price the investment can be beneficial for all parties.
The hunt for new alternative energy sources is not a hunt for a non-existing golden happy dream. The conversion of alternative energy sources into usable energy is happening today and will be better tomorrow. It is real and here to stay, for a long time.

Hydrogen Fuel Cells

Hydrogen fuel cell technology promises to help us deal with the dwindling supply of fossil fuel. But how far away is this technology for you and me?

Aren’t you tired of the high price of gasoline for your car? Not to mention your concern for the environment. Well, a solution to both of these concerns may be just around the corner. For years, scientists have being working on an alternative energy source that promises to change the way we live by changing the source of fuel for some of our most basic energy-using engines. This new technology is called a fuel cell, and it’s based on using water as the original source of the fuel! A fuel cell provides a DC (direct current) voltage that can be used to power motors, lights, or any number of electrical appliances–including cars.

The technical name for a fuel cell is an electrochemical energy conversion device. You’ve actually been using one for many years, which is a battery. All batteries are electrochemical energy conversion devices.

But hydrogen fuel cell technology is a new twist on an old theme. Here’s the basic idea of how it works:

A fuel cell converts the chemicals hydrogen and oxygen into water, and in the process it produces electricity. The difference between a simple battery and a fuel cell is that all the chemicals are stored inside the battery. The battery converts those chemicals into electricity but eventually it “goes dead” as the chemicals are used up. So you end up either throwing it away or recharging it.

On the other hand with a fuel cell, chemicals constantly flow into the cell. So as long as there is a flow of chemicals into the cell, electricity flows out of the fuel cell. Simply put, a fuel cell releases electrons from the hydrogen gas, creating electricity with the waste product being pure water! The electricity is used to power an electrical device–like the electric motor to run your car.

In an internal combustion engine, the gasoline engine burns gas and the battery converts chemical energy back into electrical energy when needed. However, fuel cells should do both tasks more efficiently.

This reaction in a single fuel cell produces only about 0.7 volts. To get this voltage up to a reasonable level, many separate fuel cells must be combined to form a fuel-cell stack.

One problem with using hydrogen is that it is not easily stored for consumer use. Other alternatives could be natural gas, propane, and methanol gas. But the primary objective of using fuel cell technology is pollution reduction. The fuel cell is also very efficient. Around 80% of the fuel used in these hydrogen fuel cells is converted into usable energy compared to only 20% for a gasoline powered engine and about 30% overall for a battery powered electric vehicle.

There is no question that the fuel cell holds great promise for the future. However, many challenges remain, and it’s been predicted that hydrogen fuel cell technology won’t be available for the masses until around 2050.

Sustainable Energy in the Home

The obvious main reason to be conserving energy is for environmental purposes with climate change already being seen across the world, the polar ice caps melting and nearer to home, the floods the UK has experienced over the past three years.?

Sustainable energy solutions within the home can come from all manner of points. Recycling of household waste, cardboard, plastic, glass and paper (trying not to buy products with so much packaging to start with). Then the changes that can be made to the actual house such as double glazing and cavity wall insulation.

An energy efficient boiler is a must for any household as an old inefficient boiler creates high energy bills which in turn will eat at more of the valuable world energy supplies. A brand of boilers which have high green credential s and are proven money savers is the Worcester Bosch Greenstar range. An energy efficient Worcester Greenstar 28i Junior Combi Boiler for example, can provide a household with all their heating and hot water needs and these boilers are dedicated to providing renewable energy solutions. Many of these boilers have an energy efficiency rating of over 90% and can often cut heating and hot water bills by fifteen to twenty per cent. The combi boilers for example the Worcester Greenstar 24i Junior Combi Boiler delivers energy saving performance by recycling exhaust gases to extract and re-use latent heat.

?Other energy saving boilers are condensing gas-fired boilers and condensing oil-fired boilers where at least 93% of the oil consumed is converted into heat for the heating and/or hot water system.

?Renewable energy devices are being introduced more frequently now in the form of solar panels and ground heat source pumps. Many of the leading plumbing and heating brands have solar panel products for the heating of hot water. Some packages can reduce an annual water heating bill by up to 60%. Solar cylinders are also available which enables a dual heat source application utilising the solar panels with one coil, and the boiler (or other heat source) with the other coil.

And finally ground source heat pump systems that tap into the natural heat found in the ground just metres below the Earth’s surface. A ground source heat pump works by keeping fluid in the evaporator slightly cooler than the source, enabling it to draw latent heat from the earth via heat collectors which are buried in the ground.
