Mr Cool asked:


When i say renewable energy i mean like solar power, wind power, hydroelectric power . Is there a certain type of engineer who works in these areas? Where is a good place to go to school for this type of Engineering.

With all this talk of the rising cost of energy and oil prices – as well as the never-ending debate of climate change – many are turning to alternative methods of generating power in order to save money on their utility bills.

There are a wide range of methods for harvesting natural energy – such as wind power, with some even converting their car engines to run off reprocessed vegetable oil, or biofuel.

Choosing to generate power from natural resources is by no means cheap, however the long term benefits still attract many to the idea in many ways – from setting up turbines at their homes to recycling materials.

There are many companies which specialize in products that capture and convert energy from natural resources, including solar power.

As technology advances, the methods of capturing natural energy have the potential to become smaller, lighter and more affordable to run.

Wind turbines have remained a much discussed alternative energy technique, with a mixed reaction from the public regarding the construction of turbines to help reduce levels of carbon emissions from power stations.

However, home turbines and solar panels are now becoming a popular addition to households who are looking to save money on their gas and electricity bills.

Indeed, many countries in the Mediterranean region make use of solar panels to help power houses and businesses.

You may think that in a country such as the UK, where the sun appears to elude us at times this could seem pretty useless. However, solar panels are not dependent on hot weather, for a small amount of energy can still be generated just from normal daylight alone.

And the equipment itself is getting lighter, meaning that installation can be simplified because of the reduction in weight. However it is still advisable to seek advice from a surveyor before deciding to install solar panels.

With the credit crunch causing increases in everything from credit cards to gas and electricity bills, people are looking for more affordable means of generating their own power in order to cut down on their utility bills.

Wind turbines store energy from a rotor, where power is generated as the blades are turned. Energy that is harvested through home turbine kits can be used as part of the energy used in your home.

Some energy companies will offer the opportunity to reduce the cost of your electricity bill by giving some of the energy back to the grid.

However it’s best to check with your neighbours before taking the decision to install a small unit on the side of your property – for what may be saving money for yourself may be considered an eyesore by others.

It is estimated that our natural resources will be completely depleted within the next 150 years. It is because of this that we as a society need to be actively searching for sources of alternative energy.

Alternative energy, whether it is used to replace fuels such as coal, or to reduce our reliance on petroleum based fuels; alternative energy is one of the most important issues facing society today.

The two most common types of alternative energy are:

* Wind power

* Solar power

Both of these alternative energy sources are harnessed from natural resources, and as such are completely free. Only the equipment and technology cost money, and over time as we advance the costs should be reduced.

It is these free sources of alternative energy that we should be pursuing with the most fervency, so that, eventually, energy can be available to all regardless of income. Below we will take a look at these two most common sources of alternative energy.

Wind Power

Wind power, while a free source of alternative energy, would be the most costly type of renewable energy to power our nation. This is largely in part to the fact that we must first place wind turbines across the country, in enough numbers to provide electricity to communities nationwide, even in areas where the wind velocity is not as strong. The cost of building enough of these turbines to harness the wind’s alternative energy would be staggering.

Also these wind turbines are very unsightly and would ruin very beautiful and scenic parts of the country. It should also be noted that they only produce power 1/8 of the time that they are running. That is not very efficient, but we are on the right track, things just need improvement.

Another problem I see with wind turbines is the amount of profit many companies stand to make for putting them in. Individuals are making millions off of this and that is just not right when our well-being is at stake.

However, if you’re interested in using wind power as your own source of alternative energy, it is a viable option. Many farms and rural communities use these wind turbines to power themselves. In smaller numbers, the cost of building the turbines pays for itself relatively quickly. But wind energy is only one form of alternative energy. Next, we will look at using solar power as an alternative power source.

Solar Power

Solar power is alternative energy derived from the power of the sun. Solar energy is also completely free, except for the cost of installing the equipment necessary to convert the sun’s rays into usable electricity. This equipment is becoming less and less expensive every day. Solar power generally ends up paying for itself within the first few years.

The equipment needed to use solar power as an alternative energy source for your home can be bought at virtually any home improvement store, and can usually be installed in just a few hours. If you don’t feel comfortable doing it yourself, there are a great number of contractors available who can install your solar panels and generators for you.

Regardless of which type of alternative energy you choose to use in your own home, the fact remains that we must find a renewable source of energy soon, or be at risk of losing the few natural resources we have left to burn. Contact your Congressman today, and ask what is being done to find a good source of alternative energy; and what you can do to help.

One of the biggest challenges the human race faces today is finding and using alternative energy sources. The push for means of generating electricity has been around for over 100 years, but when oil and coal-fired generators produced power inexpensively, the world put the search for alternative energy sources on the back burner for a number of years.

We cannot procrastinate any longer, however, as many of the earth’s natural resources, such as oil, are depleting.

A Short History Lesson on Alternative Energy Sources

The need for an alternate energy source was rekindled in the 1970’s with the oil shortage that created lines at gas stations and produced critical shortages throughout the United States. The search for alternate power generation is not limited to finding new ways of powering vehicles, as supplying cheap power for homes and industries is a continuous endeavor. There have been many advances in the search for alternative energy sources, but the price of the power produced still remains too high.

Wind, water and sun are touted as renewable energy resources with claims that once the technology is perfected, making it more cost effective, they can replace the need for oil and natural gas to turn turbines in the generation process. Even geothermal power production is one of the alternate energy sources being researched.

The Source Of The Energy Depends on The Location

For many people the switch to alternative energy sources is a matter of finding the type of alternative power that works the best in their particular geographical location. Persons who live in areas that have limited exposure to the sun for example, may not be too excited about using solar panels to supply power. When the sun goes down for an extended number of days, the town can go dark.

In some of those areas, wind is not a problem as it seems to blow nearly every day. Using wind power to turn turbines to generate electricity can work there, but may not work in other areas that experience less windy conditions. Another of the alternative energy sources, hydropower uses the power of rivers to turn generators, but the cost of the infrastructure to get power to the people from the generator may still be high for long range use.

With the three major alternative energy sources continuing to be researched and advanced, the need for an answer to out problem becomes more evident every time a person receives their electric bill, or fills their car with gas.

The resources that we have left on the planet are running out. Do your part to keep educated on the latest changes in technology and any up to date with the issues at hand to learn what you can do to help solve the energy crisis.

Chaosman asked:


Why not build an office building sized electricity generating station in a major city that incorporates – the entire outside of the building is covered in super-efficient solar panels, the top of the building has a solar heat generator, the bottom of the building has geothermal heat generating power, a giant wind turbine at the top generating wind power…any others that could be added to a building? I wonder if it would generate a decent amount of energy?
