Solar power and wind energy
We hear a lot about so-called renewab
le energy in the modern world. As the effects of global warming – or climate change, depending on your preferred terminology – become more apparent, the need to find a way to generate energy without damaging the Earth becomes all the more important.
One of the most talked about methods of making energy is solar power. As the name would suggest, solar power involves taking the energy of the sun and using that energy to generate electricity on Earth. While solar power is not a new concept, it is nevertheless looking like it will receive much focus during the search for renewable energies.
Solar power works by concentrating the heat of the sun in a specific place. To do this, solar panels or heliostats are erected in the sun’s glare, where they capture heat. The surfaces of these panels are usually mirrored or shiny, so as to increase the already potent heat of the sun. This heat is then used to generate electricity through a variety of methods; the most common of these is to use the heat to boil water and general steam, which is then used to power a traditional electricity generator.
Solar power is not infallible as a technology, but it is more reliable than was first previously thought. Despite popular conviction, it is possible to generate electricity using solar panels on overcast days, which opens the technologies up to most countries. For solar power to be truly effective, however, the panels need to be placed where they receive continual sunlight and heat throughout the year. For this reasons, countries such as Spain are becoming the pioneers of solar power – though their scientific advances will eventually benefit us all.
How Reliable Is Solar Power? With solar power being flaunted as one of the realistic alternatives to the burning of fossil fuels, it is only natural that enlightened thoughts are turning to the reliability of the energy it can create. After all, the sun is an intermittent energy source. It does not always shine, with most countries experiencing cloud cover for large portions of the year. There is also the issue that the sun is only available for, at most, 12 hours out of every 24. Could the world’s energy demands really be sustained from what seems like such an unreliable heat source?
The answer is probably no, which is why solar energy is only being spoken of as one of the options for continued energy production. However, solar energy is one of the most viable of the options mentioned, even if it could not meet the entire world’s demands for energy by itself.
The reason for this is simple; the sun is a constant. The sun will continue to shine for as long as there is life on earth; by the time the sun begins to dim, the earth as we know it will begin to die. Unlike the expendable resources of coal and oil, this makes the sun very dependable – it will be here for as long as the world will.
The sun is also relatively easy to ‘tap’ into, as it shines directly onto earth and needs no human interaction for it to work to its full potential. While manufacturing solar panels can be expensive, they are relatively hassle free once created, and the only engineering they require to function is to be pointed as directly as possible toward the sun. This is certainly more viable than having to dig into the earth for coal, or send rigs out to sea to collect oil.
Solar power is, therefore, a reliable energy source. How effective it is a matter of debate, but one should largely assume that much – if not all – of the world’s demand for energy can be satisfied by our most powerful celestial friend.
Solar Power – cutting your energy bills and saving the environment, the concept of solar generated energy has the kind of truths behind it that would make the vast majority of advertising executives salivate.
Firstly, the environmental considerations of using solar energy are huge. With fossil fuels, such as coal and oil, set to run out at some point; there has been a renewed focus in finding sustainable and renewable energy. Solar power has come to the forefront of such discussions as a viable alternative to the old ‘digging stuff out of the ground and burning it’ way of generating energy.
The effect this ability for renewable energy which takes nothing from the earth itself is huge. While solar power will never be able to meet all of the Earth’s energy demands, it should certainly be able to sate a large portion of the populace. By switching to such renewable energy that capitalizes on a natural resource, the environmental impact would be significant.
Secondly – and this is where the aforementioned advertising executive would really become excited – solar power could save the average member of the population money. By having solar panels installed, people could save as much as 30% on their usual electricity and heating bills.
With every year that passes, the general populace becomes more concerned about their own impact on the environment and their own dependence on fossil fuels. As time passes, these people with particular concerns are looking at utilizing other forms of energy. Once upon a time, seeing solar panels on the roof of a normal home would have been alarmingly unusual, but it is now fast approaching the norm. The average household is now capable of saving the environment and saving money – what are you waiting for?
Would Solar Power Save You Money? You’ve probably heard it all before; solar power is the answer to the world’s energy crisis, and what’s more installing solar panels in and on your home will save you money on energy bills. With utility bills, particularly electricity, increasing all the time – it’s no wonder that more and more people are seeking alternatives.
So, basically, the blurb is good. Solar power is good, and it is truly a way forward. At this point, with interest piqued, many will begin to wonder if they genuinely can save money and the environment by investing in solar panels.
Solar panels can be placed anywhere; the most effective place for the average household is on the roof, where exposure to sunlight is at its highest. And while you may feel the stories of cut price energy bills are a little bit too good to be true, the simple fact is by switching to solar power you will save money. Yes, everyone.
Solar panels can replace your dependence on electricity and gas – two of the most used utilities in any given home. For the first few years what you save will be largely offset by the cost of the solar panels being installed, but most companies estimate that people will genuinely be saving money by their seventh or eighth year with solar panels. Reduction in energy bills could be as high as 30% – no matter what or who you are, from a tiny flat to a large six bedroom detached house.
Purchasing and installing solar panels should be seen as an investment rather than a quick fix for your energy bills soaring.
