Does The US Government Care About Solar Power Systems?

August 28th, 2010 No comments

Green energy is a term, which refers to energy generation with the help of renewable sources like the sun, e.g. homemade solar panels.

No one can deny that this technology must be used soon as, in several years; we will run out of natural sources like coal, gas, etc. To focus a spot of light about solar panels, let us consider in this article what the plan of the US government is.

How does it look like in the United States?

Indeed, advanced countries like the United States paid attention to this problem early enough. In the USA, the government set a plan to get around 2.5% of its energy needs via solar systems by the end of 2005.

In the meantime, they achieved more what they planned as the government gets more than 5% of its needs using green energy. Even better, you will find there some nice courses about how to build your own solar panel system.

What are the sources used for energy production?

Indeed, they do not rely solely on the sun light. Rather, they use also windmills, biomass plants, recycling, etc. You should be also informed that the US government teaches its employees how to reduce the consumption of energy.

Furthermore, a governmental organization will be rewarded, if it opted for green energy.

In reality, there is a big need to consider this problem seriously especially in the winter, when the consumption is high due to heating purposes. However, in some hot places, the load will be higher in summer due the usage of air conditions.

So, in other words, green energy is useful the whole year time. You can start by yourself and power your house using the sunlight in summer. Why do not you opt for (DIY) do it yourself solar panels?

What is the true surprising fact?

One more nice fact about green energy in the US is the ambitious plan to get around 7.5% of the energy needs from renewable sources. This should be accomplished by the year 2012 or 2013.

To achieve this goal faster, the government encourages the citizens to opt for DIY solar panel kits to save their money paid to power companies.

What is the future of green energy?

In a nutshell, green energy is the future. What will we do in 10-20 years, when we ran out of coal and gas? I would strongly advise you to start now to contribute in saving energy and keep your environment pollution-free. By this time in few months, you may be able to use solar hot water systems.

So, on the way to this nice goal, you should devote enough time and energy to look now how to build your own solar panels.

Concentrating Solar Power Systems: Your First Guide!

June 23rd, 2010 2 comments

Are you still wondering why many people like to have mirrors on their fields that point toward the sun? The answer is these people are looking to build a solar power system.

The idea behind these systems is to concentrate the sunlight to one spot and, accordingly, the heat focused can be used to heat up the liquid that flows along the pipes.

This system is well-known as Parabolic-trough system, which plays the role to heat the oil that is flowing through the pipe. As the oil is extremely hot, it makes sense to use it to boil water to power a steam generator, which in turns powers the needed electricity.

Why do people opt for this system?

The big deal behind these systems is the U-shaped mirrors. They do an excellent job in attracting and collecting the sun heat, which is then transferred onto the receiver.

The receiver absorbs the heat and transfers into fluid, which helps to power the engine.  The heat causes the fluid to swell up against the piston and that produces mechanical power.

What are the typical applications for this energy?

There is no unique answer for this question as you can use this system for any application that needs power. For example, operating generators or even an alternator can be typical examples of this method. Indeed, this system works fine, thanks to the molten salt that flows through the receiver.

When the salt heats up, it can generate electricity through the steam generator.  The salt holds in the heat for several days before it has to be converted into electricity.  Because this system uses so many panels, it is mainly used for industrial solar power where acres of land can be donated to the Parabolic Trough.

What is the big benefit behind this system?

Indeed, this system does not have to work every day to generate power. Such systems are large enough to create energy that will be enough not only for a single day, but also for several ones. Practically, this system is large enough to permit the transfer of the heat a couple of days later.

Why should you opt for this option?

Business owners do opt for concentrating solar power systems as they will never run into the problem of having long down-time when the power fails. They do care about their machines in the first concern, and as long as the machines can still work, nothing else will worry them.

What is the direction of the future?

Scientists are continuously studying this theory as businesses use it to power their machinery.  Steam power was what was used from the beginning with solar power and is still what most systems depend on to service their production needs.

In fact, experts expect to see more and more fields that full of mirrors pointing up to the sky. The motivation is surely generating solar energy that is enough for the whole world. This is indeed a great goal since traditional ways of getting electricity are getting more and more expensive.
