Solar Power For Homes

By Adrian Fletcher

Solar power for the home has made great strides since its early beginnings. Technological advancements have allowed commercially available building materials to incorporate solar cells, which turns them into solar panels that are virtually invisible to the naked eye.

There are two ways that solar power for homes is supplied. These are off-grid and on grid or net metering. A stand alone solar power system acts as the sole source of electricity for your home and is off the grid as such. Alternatively, supplemental solar power systems, can supply all of your homes energy depending on sunlight availability. When sunlight is not available, your home can use energy from the power grid.

Standalone solar power systems and supplemental systems for the generation of solar power for homes contain the same fundamental parts. At the outset are the photovoltaic panels, generally referred to as PV or solar panels, which are equipped with a solar cell or semiconductor that transforms the sun's rays into electricity. The electricity then is routed to a regulator/controller which maintains the electric current at the voltage/amperage level the system is made for. Electricity then is routed into your home's electrical system or else into a battery array or a storage system which will keep the solar power ready for when the sun sets.

If your home is connected to a power company grid you do not have to install a storage system, but it does have its advantages as it will help to further lower your monthly utility bill, and it will make power available to you during a power outage.

It is now cheaper and simpler than ever before to reduce or eliminate your need for outside electricity by using solar power for homes. Several types of building materials include awnings, roofing materials, car port roofing, and edges of window panes. This kind of solar panel is known as Building Integrated Photovoltaics. If used for roofing material, such panels provide the same measure of home protection as do asphalt shingles, even while they function as a solar panel.

One of the greatest obstacles to using solar power for homes has traditionally been the up-front expense. Now, however, there are avenues to offsetting that expense. Government grants are available which go a long way toward subsidizing your household's conversion to solar power. Federal rebates for solar power installations can vary year from year, and each state that offers one has its own incentives ranging from additional rebates to offering low-interest rates to finance green projects.

Besides the fact that you'll make your home greener using solar power for homes, you'll also be seeing lots of "green" with all the savings on your utility bill. You may even be able to eliminate a utility bill altogether. A growing number of utility companies now have a metering program allowing you to sell to the power company any excess power produced by your solar power system. Selling your excess electricity to the power company is a good idea and more net metering programs will be enacted in various states in the future. An incentive to sell your electricity to the utility company benefits other people that can use the power and reduces the utility companies need on coal and other fossil fuels to generate electricity.

The Future Of Biofuels

By Mike Sullivan

Biofuels are fuels that can be created when some biological materials decompose. They are primarily derived from plants, and can be formed as solids, liquids or gases.

Bio-fuels are different from fossil fuels in the following ways: 1. Fossil fuels take millions of years to make whereas bio-fuels can be made extremely fast, in a matter of days. 2. Fossil fuels generate huge amounts of pollution. Bio-fuels are comparatively safer. 3. Bio-fuels are renewable sources of energy unlike fossil fuels.

Bio-fuels have been categorized into four types: first generation, second generation, third generation, and fourth generation.

The first generation bio-fuels are derived from vegetable fats, starch, and sugar, which are in turn derived from food-crops. The first generation fuels are also derived from animal fats. Biogas, bio-diesel, and vegetable oil are some examples of this type of bio-fuels.

The second generation of bio-fuels is mainly derived from waste biomass, thus making it a more balanced option compared to the first-generation bio-fuels. Different kinds of alcohols and diesel generated from wood fall into the category of second generation bio-fuels.

The third generation comprises of bio-fuels derived from algae. Algae are farmed on large scales for creating these bio-fuels. The algae fuels are extremely environment-friendly as they can easily decompose into the soil without harming it.

The 4th generation of biofuels are those made from excretions of microorganisms. The microorganisms are farmed in large scale reactors and excrete chemicals that can be used as fuel.

Advantages of biofuels include: 1. They reduce the burden on fossil fuels which will one day run out. 2. They are eco-friendly, unlike many bio fuels, and will help reduce carbon dioxide emissions. 3. They can be very cost effective when used correctly.

Disadvantages of bio-fuels include: 1. Economists have long debated on the usefulness of first generation bio-fuels when compared to the food that could be grown instead. Generating fuel from food crops makes food crops unworthy of human consumption. Some people believe that being a higher priority than fuel, food should not be farmed for making fuels but for human consumption. 2. Making bio-fuels require acres of farming land, thus encroaching upon the natural habitat of plants and animals.

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.

Do We Need To Find Alternative Sources of Energy?

Is there really a need to find alternative sources of energy? I believe there is. The problem we face is figuring out how to tap into the renewable, natural resources we have. The pollution from using fossil fuels and from nuclear waste is going to have consequences to us and to our environment. Just what alternative energy sources are available?

Solar Energy

Solar energy is just energy from the sun that is converted into electricity using a process called photo-voltaics. Solar power has been used for quite some time and can give us electricity for homes and buildings. It can also be used as fuel for vehicles, for solar cookers, in metal smelting, and to make industrial chemicals.

Hydroelectricity

Hydroelectricity is the most commonly used source of alternative energy. This type of power is made by utilizing the gravitational force of water falling from a high place. Here's the good news; hydroelectric plants do not create toxic by-products and don't emit many greenhouse gases. Dams can be expensive to build and maintain, but the benefits of a hydro-electric plant outweigh the cost in the long run.

Wind Energy

Energy that comes from the wind is renewed each time you use it and won't cost you much at all . Wind power can be used in agriculture to pump water or grind grain. We can harness the power of the wind to run our homes and the various 'gadgets' we seem to have so many of.

Geothermal power

Heat from below the earth's surface produces geothermal power. From an economic standpoint, this form of energy is more feasible than using fossil fuels that have rising costs. One large geothermal plant could power a whole community. Geothermal plants run a lot cleaner and don't release a lot of poisonous gases into our air.

These are the more common and environmentally friendly alternative energy sources. I think we need to explore these options and implement them as much as we can.

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!

Make Your Own Windmill - Slash Your Electric Bill!

Traditional sources of energy could soon be a thing of the past. We need to change the way we get our energy and consider how much energy we are using in order to attain a more sustainable lifestyle.

There are many people who have already begun to do this. Previous problems with renewable energy have largely been solved due to new breakthroughs in engineering and technology.

With a good guide, even homeowners inexperienced in construction can create their own renewable energy sources, such as wind power generators. Wind turbines can reduce the average home's electricity bill by as much as 70-80%.

They can be built for as little as $200 using pre-used parts. The most expensive part might be a DC motor which can be as cheap as $30. You can find most of the materials you will need at your local hardware store and build it using a few basic tools.

The average American home can use from 14-20 kWh a day. If you start using a plan to conserve power, you will use much less than you are using now. Even if you don't have a lot of wind in your area, you should be able to reduce your power bill significantly with the use of a wind power generator.

Alternative Energy Sources

Alternative energy sources may be one way we can stay ahead of the rising costs of energy. I don’t see these costs going down anytime soon. Are you tired of paying more every time you turn around? I sure am! What else can we do? One thing I have been doing is exploring how I can use more renewable energy sources and other ways to have a ‘greener’ lifestyle.

It used to be that alternative energy sources for your home such as wind power or solar power were so expensive that the average homeowner couldn’t afford to have them installed. Many people have looked into the cost of solar panels and ran away screaming when they see the cost! Fortunately there are step-by-step instructions available now for the homeowner to convert over to solar or wind power at a fraction of what it used to cost them.

The amount of energy we use in our homes is at an all time high. Some people are very frugal with their energy use, while others don’t seem to care if they waste electricity or gas. I have decided to save myself some money and use more alternative energy sources around my house. From what I’ve learned, it can save me at least 50-80% on my fuel bills. That sounds pretty good to me!
