Photovoltaic cells-those black squares an array of which comprises a solar panel-are getting more efficient, and gradually less expensive, all the time, thanks to ever-better designs which all them to focus the gathered sunlight on a more and more concentrated point.

The size of the cells is decreasing as their efficiency rises, meaning that each cell becomes cheaper to produce and at once more productive. As far as the aforementioned cost, the price of producing solar-generated energy per watt hour has come down to $4.00 at the time of this writing. Just 17 years ago, it was nearly double that cost.

Solar powered electricity generation is certainly good for the environment, as this alternative form of producing energy gives off absolutely zero emissions into the atmosphere and is merely utilizing one of the most naturally occurring of all things as its driver.

Solar collection cells are becoming slowly but surely ever more practical for placing upon the rooftops of people’s homes, and they are not a difficult system to use for heating one’s home, creating hot water, or producing electricity. In the case of using the photovoltaic cells for hot water generation, the system works by having the water encased in the cells, where it is heated and then sent through your pipes.

Photovoltaic cells are becoming increasingly better at collecting sufficient radiation from the sun even on overcast or stormy days. One company in particular has developed solar collection arrays for the home that work well on inclement days, by way of a technologically more advanced system that stores more energy at one time during sunlit days than previous or other arrays.

There is actually another solar power system available for use called the PV System. The PV System is connected to the nearest electrical grid; whenever there is an excess of solar energy being collected at a particular home, it is transferred to the grid for shared use and as a means of lowering the grid’s dependence on the hydroelectrically-driven electricity production. Being connected to the PV System can keep your costs down as compared to full-fledged solar energy, while at once reducing pollution and taking pressure off the grid system.

Some areas are designing centralized solar collection arrays for small towns or suburban communities.

Some big-name corporations have made it clear that they are also getting into the act of using solar power (a further indication that solar generated energy is becoming an economically viable alternative energy source).

Nations such as Japan, Germany, the United States, and Switzerland have been furthering the cause of solar energy production by providing government subsidies or by giving tax breaks to companies and individuals who agree to utilize solar power for generating their heat or electrical power. As technology advances and a greater storage of solar collection materials is made available, more and more private investors will see the value of investing in this “green” technology and further its implementation much more.

Although it is much less expensive to initially get hooked into the local electric company’s grid than it is to set up and hook into wind turbines, in the long run one saves money by utilizing the wind for one’s energy needs-while also becoming more independent.

Not receiving an electric bill while enjoying the advantages of the modern electrically-driven lifestyle is a wondrous feeling.

Electric bills and fuel bills are rising steadily but the cost of wind turbine energy is zero, and the cost of installing and hooking up a turbine is steadily coming down as demand rises and more commercial success is realized by various companies producing the turbines and researching technologies to make them ever more efficient.

In addition, people are moving away from the traditional electric grids and the fossil fuels for personal reasons including desire for greater independence, the desire to live remotely or rurally without having to “go primitive”, political concerns such as fears of terrorist strikes on oil fields or power grids, or concerns about the environment.

Again, this motivation to get away from the traditional energy sources is the same one that causes people to seek the power of the wind for their energy, giving more business opportunities to profit from wind turbine production and maintenance, which drives their costs down for the consumers.

In nearly thirty states at the time of this writing, homeowners who remain on the grid but who still choose to use wind energy (or other alternative forms) are eligible for rebates or tax breaks from the state governments that end up paying for as much as 50% of their total “green” energy systems’ costs.

In addition, there are 35 states at the time of this writing where these homeowners are allowed to sell their excess energy back to the power company under what are called “net metering laws”. The rates that they are being paid by the local power companies for this energy are standard retail rates-in other words, the homeowners are actually profiting from their own energy production.

Some federal lawmakers are pushing to get the federal government to mandate these tax breaks and other wind power incentives in all 50 states. Japan and Germany already have national incentive programs in place. However, “A lot of this is handled regionally by state law. There wouldn’t really be a role for the federal government,” the Energy Department’s Craig Stevens says.

And as might be imagined, there are power companies who feel that it’s unfair that they should have to pay retail rates to private individuals. “We should only have to pay you the wholesale rate for your electricity,” according to Bruce Bowen, Pacific Gas & Electric’s director of regulatory policy. However, the companies seem to be more worried about losing short term profits than about the benefits, especially in the long run, of the increased use of wind turbines or wind farms.

Head of the Center for Energy Efficiency and Renewable Technologies of California vs John White points out, “It’s quality power that strengthens the grid.”

It does not really matter whether your home gets flooded by water from a natural disaster or because of faulty or damaged plumbing. It can happen at almost any time of the year and it is never pretty. It can be from mild flooding of a few inches localized to one or two rooms or it can be as bad as one or two feet from excessive rainfall flooding or even a creek or stream overflowing nearby your home.

It the flood happens while you are home, believe it or not this can be a good thing. It is always worse if you have flooding going on and you are away from and not able to even try to stop it. When the flood is occurring because of a plumbing break, it is possible to get the water off and begin getting it out immediately. When it a natural disaster flood you usually have to wait until the water recedes outside before you can start getting it out of the house. Removing more than an inch or two of water can be a huge undertaking to try and do yourself and the longer it takes to remove the water and dry out all of the affected surfaces, the bigger risk you run of mold developing and other unpleasant surprises.

If you have hardwood floors, as so many people do these days, if they are not dried out properly they will warp and buckle. When this is allowed to happen, the affected area will probably have to be torn out and replaced. If there is still moisture underneath the floor even after the top may appear dry, this is where mold might begin to grow. If you ignore this issue, it could end up destroying a lot more of your home than you realized.

It is usually always better to enlist the help of a professional water damage team when you have even mild flooding. By doing this you can rest assured that any problems that can arise because of flooding will be taken care of in the right way with the best equipment available. Water damage professionals are able to dry your floors and walls quickly and properly to help prevent any warping, buckling, rotting, or mold infestation.

Flooding from a plumbing break is almost always covered by a home owner insurance policy. They will need to be contacted as soon as the damage is discovered. If you have a flood caused by a natural disaster, this can be a whole new ball game. Home owner policies generally do not cover this type of flooding and having a separate flood policy that will cover natural disasters is the smartest thing that you can invest in before you might ever have to use it.

Wind power has been an effective energy source for nearly twenty years. At the end of 2007, worldwide capacity of wind-powered generators was over 100 gigawatts. It accounts for upwards of 19% of electricity production in countries like Denmark.

What is Wind Power?

Wind power is the transformation of wind into energy, usually in the form of electricity. Wind technology brought the Nina, Pinta, and Santa Maria to North America in the 1400’s and ran Dutch wind mills, so it is well-established in terms of its potential. Farmers have used wind power to pump water. Human beings have known about the power of wind for a long time and have been using it for thousands of years.

In recent years scientists have determined that the use of fossil fuels can not continue as a permanent energy solution. Oil is being used up at a frightening rate and coal pollutes the environment worse that probably any other fossil fuel. We must look towards wind, solar, water, and electricity to power our future. Today we will examine wind power, its benefits, its downsides, and its future.

What Are the Downsides to Wind Power?

As long as sailboats roamed lakes and oceans, sailors knew what the main problem with wind is: it stops. When the wind stops, the ship stops and the same is true with electricity. Yet there are places where the wind is fairly constant and where wind farms can be established-large pieces of land that hold many wind mills and can therefore generate quite a lot of electricity. To rely solely on wind power would require many batteries, high capacity storage units, and might be frustrating in some seasons.

The most polluting aspect of wind power is in the construction of the wind mills. Modern wind mills are made from high tech materials, which can be expensive. Yet after the wind mills are constructed, they can make up for their carbon footprint and then continue to generate “green” power for a long time. Large commercial windmills are also dangerous to birds, which poses a threat from animal advocacy groups.

What Are the Upsides to Wind Power?

Wind is known as a renewable resource. Unlike oil or coal, which is finite in terms of the amount, the wind goes on as long as the Earth is here. We wouldn’t have to worry about running out of wind on a permanent basis, even if it dies down once in awhile.

Relative to other energy sources, wind power is the least polluting alternative energy choice.

Because the sun is often shining when the wind is down and the wind is often high when the sun is not shining, a combination of solar power and wind power would be ideal to help people kick the petrochemical habit. The United States has experienced two oil crises in the past thirty years-one in the 1970’s and the one just recently. Wind power could help us solve this dependence sooner rather than later.

What is in Store for the Future of Wind Power?

Forward-thinking people are looking to wind power and solar power to generate power to accommodate our ever-increasing need for electricity. Already wind mills are available to the public; at this point they are fairly expensive. But as people adopt them, they will probably be like computers-expensive at first but eventually providing more and more power for less and less money.

The future of wind power looks bright. As with computer chips, energy conversion and storage will continue to improve. It is quite possible that within the next 20-30 years, wind power will produce as much as 100% of the energy demands of the US. This would have to be an aggressive effort with optimized wind power stations, and continuous research on improving the conversion rate. The best news of all though, is that between wind and solar power the US does have a sustainable, renewable alternative to fossil fuels.

Global warming is an urgent, but solvable problem. That is why we have joined the We Campaign, a powerful nonpartisan movement of concerned citizens that was founded by Nobel Prize Laureate and former Vice President Al Gore. Read on to find out how easy and safe it would be to implement a renewable energy solution for America.

Given the tentative speculations that in 10 years oil will no longer be available to us in the quantities we require, we must strive to produce 100% of our electricity via clean and renewable sources by that time. Oil is not the answer and coal is not the answer.

Here are a few reasons we need to move away from coal and oil, and start investing in renewable resources:

* Even today, half of our electricity is produced by coal rather than oil. OK, but what you may not know is that coal is a top contributer of global warming, and negatively impacts the environment in many other ways. We need to abandon this archaic source of energy for something much cleaner.

* Even ‘clean coal’ power plants do not prevent carbon molecules from being released into the atmosphere. They are absolutely no help to the global warming / clean environment cause.

* Early in 2008, Saudi Arabia committed to producing more oil to alleviate high oil prices. OK, but what you may not know is that since that time the price of oil has actually increased. America has no effect at all on the price of oil. We need to relinquish our dependence on it 100%.

* Wind power is a clean and renewable source of energy. OK, but what you may not know is that the potential for wind power in the US would provide more than 5 times as much electricity as we currently use. In fact, North Dakota alone can provide 33% of the total electricity required by America today.

* Solar power is another clean and renewable source of energy. OK, but what you may not know is that we can harness enough solar power during the day to provide all the necessary electricity needed to operate at night. In fact, by laying solar panels on a 100 square mile patch of land anywhere in the US (think desert land), solar thermal facilities could provide 100% of our electricity needs, day and night.

So, what does that tell you about clean renewable energy resources? By combining wind power, solar power, and by developing additional alternative energy resources such as Ethanol powered and hybrid vehicles, the US could potentially be free of environmentally and economically damaging sources of power.

Support the Challenge

It will certainly take more than just one man to stand up for this movement. Please do your best to support America in this time of energy crisis. Do it for the Earth, for your kids, for your kid’s kids, but most of all do it because it’s the right thing to do.

Al Gore just challenged the nation to take bold steps towards solving the climate crisis. Join the We Campaign and support a movement to more efficient, clean, alternative energy.
