Using Wind Power To Get Off The Grid

By David Sullivan

Today the catch phrase is going green. Everyone is interested in ways they can be kinder to the planet and still get their energy needs met. Wind power is a renewable energy source and a simple wind turbine will provide power for many years.

Generating electricity with the use of a wind turbine is a good alternative or supplement to solar power. If the sun isn't shining, the wind will likely be blowing. You can save money if you build the wind turbine yourself.

The whole family can help out. If you want to take it further, try to use recycled materials where it is feasible. You can get the parts you need at your local hardware store for less than a couple hundred dollars.

Blades can be made of wood, cardboard or PVC piping. The blades need to be the correct weight for the size of turbine you're making. The base can be made of a wooden or metal pole.

Before you begin, find a good manual that will explain how to build a solid structure. The manual should give you detailed building instructions in a format that is easy to follow. Step by step instructions are the easiest to follow. The manual should include a list of all the materials you'll need to build your wind turbine. Some manuals will offer you alternatives that you can use for building materials. The book should give suggestions on where you may find the needed materials, but you should be able to find most at your local hardware or home improvement store.

Building a wind turbine can be done with some basic knowledge and familiarity with simple power tools. It is a great way to make use of some open space around your home. A wind turbine can be constructed anywhere that the wind will blow. It is a great way to become an active participant in the green movement.

If you have an acre of land or two, you can even build more than one and send energy back to the grid. Your power company will pay for the energy you send to them.

Many people may be missing out on an important and easy to implement way to conserve energy. It is not difficult to do if you have a good set of instructions. You will be doing your part to conserve the environment while cutting the cost of your electricity.

Renewable Energy - Is It Too Late?

By Eric Q. Duncan

Renewable energy, what could really be the right definition? As it is the general term for many different unconventional energy sources, it has to be all-encompassing. Gurus tell us that renewable energy is an energy source that we find naturally and to a great degree.

Most renewable energy sources are dependent on nuclear power. This nuclear power comes from the sun. In a huge nuclear reaction, the sun produces energy in the form of light and heat and this reaches the earth as natural sources of energy. The sun is the ultimate source of solar power, wind power, biomass energy and so on. Fossil fuels may be categorized under biomass energy, but are limitedly available and have plenty of disastrous side effects.

The US federal National Renewable Energy Laboratory has a good renewable energy program that researches the latest energy-saving building techniques. Scientists have realized that energy efficiency is the way to go, and this body educates people in this aspect.

They work together with the leading instances of the building industry, foreground endeavors to build using renewable energy and tell producers as well as consumers about what and how they can save money by using this form of energy. NREL also get together with agencies to set guideposts for buildings and other energy consuming gadgets.

Renewable energy use is beneficial for the environment in the polluted world of today. Wind and solar energy are two of the most prominent types of this energy. Biofuels, geothermal energy and wave or tidal power are fast becoming popular, though some of these may potentially harm the natural world.

Can you tell the difference between renewable and alternative energy?

Many people don't know the fine difference between the two. Renewable energy is fundamentally natural; it's the energy we get from the sun, wind or waves. Alternative energy, however, includes both bio fuels and nuclear energy sources which are not really healthy options for us to use.

The infrastructure we have is suited for fossil fuels, even though renewable energy or green energy more cost effective. Our government has not been busy taking any steps to change things and go in for green energy sources. With the present situation worsening every day, we have to get a change really soon.

If we try to find one positive thing about fossil fuels it could be that we can store the energy we get from them, which is more difficult with green energy sources. Solar power, for instance, is less effective in cloudy weather. Calm days there is not very much use of a windmill. This and initial costs to get energy from these unconventional sources are still a bit high, could be a small drawback as compared to traditional earth-killing sources of energy.

Benefits Of Sustainable Development

By Tommy Linsley

"Every fourth day we are adding one million human beings to our population". After hearing this statement, how you have felt? That's the burden we the human beings are putting on the natural resources of our planet. We have already made many animals extinct and driving rest to the extinction. The unplanned growth has resulted in cutting down of forest, blasting off of mountains, mining of minerals and metals, using up of petroleum resources at a very fast rate and last but not the least, an exponential increase in pollution.

The question is what we are going to leave for our future generations - the barren lands, vehicles but no petrol, factories with no power to run them, mountains of concrete and jungles of sky touching building? Can it be recognized as development? Is this development that can be sustained? We all are aware of the negative answer.

The development that we are pursuing has already taken toll of wild animals, forests and much of our natural resources. The increased pollution has resulted in global warming, ozone layer depletion, rising of water level in seas, melting down of snow at mountains and more recently at North Pole!

The constant erosion of forests has resulted in loss of habitat for the wild animals. No wonders that now and then we hear the incidents of wild cats being found in cities. They are considered dangerous and killed. But the fact is that human population has grown in a disproportionate quantum and has moved closer to the animal habitats.

So what should be the plan of action to preserve the humanity of the earth? The only way is to preserve the ecological balance. We need to protect the wild animals, forests and natural resources. Governments need to plan to cover more areas under the forests. Every individual should make an effort in that direction.

The increased pollution levels are already serious matters of concern. During peak traffic hours, one might see some people wearing pollution masks. This is in contrast to what we felt at mountains. We are responsible for such high levels of pollution in air and in water.

It is time that the ecology is preserved to make the development-sustainable development. Alternative sources of energy have to be used to relieve pressure from the natural resources. Solar power is being used to convert it into solar energy; similarly wind power has been translated into wind energy. Recycling of paper can be a lifeline for trees. Developing renewable sources of energy can help in longevity of natural resources like coal and petrol. Vehicles, using non-conventional energy resources can help in keeping low pollution levels.

With our combined efforts, we still can restore the right balance of ecology. Only with a green earth, we can hope for a sustainable development.

Save The Environment and Your Money With Solar Panels

By Thomas Murphy

The largest sources of energy that we are currently using will eventually run dry. As we run out of non-renewable sources of energy, they are also getting more expensive. Renewable sources of energy are the way of the future but many people still don't believe that it is cost-effective for their own homes.

Costly and Complex? Not anymore!

Getting somebody to install your own solar panels for you may cost more than $3000 dollars. But it's easy to learn to install your own!

There are many guides on the internet that you can read to learn how to do it, and save yourself thousands of dollars. Solar panels can be installed on the roof of your house and can save you 80% or more on your electricity bill.

Many of these manuals are easy enough that anybody with basic knowledge of tools and access to a hardware store can do it. Alternative energy is low-maintenance and low-cost, and the price is dropping every day due to better technology.

Government Supports Solar Power

Any manual worth the price should show you how to do this.

A lot of governments are realising the importance of renewable energy, so many of them offer support for those who install it. You can get thousands back from the government, depending on the scale of your project, no strings attached.

Power Companies Will Also Give You Money

If you produce more electricity than you use, your power company will give you a check! Putting more energy into the grid with renewable energy helps reduce the use of earth-consuming energies like coal.

Save the Environment But Don't Pay The Price

So you can sit and watch TV shows about global warming all day or you can be one of the people who actually goes out and does something about it...

Now that you can actually profit from going green, you have no excuse!

Wondering how to get started?
