Is A Solar Panel Electrical System Right For You?

Thursday, May 26th, 2011

Until approximately a hundred years ago in the West, people only had recourse to renewable energy for heat and light for their homes. They burnt wood and sometimes coal or peat (OK, fossil fuels) and got up when the sun came up and went to bed with the sun too. In, fact a large part of the world’s population still lives like that.

Things changed with mechanized industry and night shifts. Electricity providers sold the populace on being able to do more instead of just sleeping when it got dark, and the Western population got hooked on buying huge amounts of energy, mostly electricity and engine fuel, which was usually produced from oil and coal.

This idea soon travelled around the world and with rising affluence came emulation and other countries wanted the same. Now we are in the sad predicament where we have to admit that we rode the fossil fuel gravy train to its last stop without thinking about what we would use when fossil fuels ran out.

This is where the typical civilian comes in. You have to think about how you want to draw energy in the future. Do you want to be powered by keeping sucking unrenewable resources out of the Earth, or do you want to have as little to do with it as you can? Would you prefer to have everything you have now, but know that the resources that are powering your lifestyle are renewable?

If, like millions of others around the world, you would rather say ‘No!’ to traditional power production methods, then you have to take a stand. But not only in words, you really have to do some something about it physically.

This will mean paying a lot of money up front, which may not be a problem for you or you may even think that taking a stand is worth looking for a bank loan. These are commendable feelings, but I would like to suggest that there is another way to self-sufficiency.

You could build your own!

Why not? The technology has been around for decades and is fairly easy. Most reasonably competent teenagers can put together a bank of photovoltaic cells into a solar panel and then plug that into your home’s electrical system. And if a teenager can manage it, so can you. All you (and the teenager) will require is a solar panel kit and a schematical diagram. A plan in other words.

A solar panel kit can be bought locally from a Do-It-Yourself shop or from the Internet. A typical solar panel will take a few hours to fit together and will produce 100 watts of electrical energy. The electricity produced from these panels is then passed through an inverter that changes the current from DC to AC, making it usable by household appliances and the utility grid.

Do yourself and the planet a good turn, get off the grid and start saving money and the planet’s resources, you will be surprised how easy it is once you get going. And do not forget, you can do it in stages of, say, one 100 watt panel a month until you hit self-sufficiency. It is not a question of ‘All or Nothing’.

There Is Life Off The Grid

Wednesday, April 27th, 2011

You can live off the grid. You only have to have the grid to purchase electricity if you cannot generate your own. Living on the grid has made too many of us lose our self-sufficiency. We slavishly buy energy off the big suppliers and pay through the nose for it at the end of the month.

How many days a month do you have to work just to pay your electricity bill? What could you do with that time or money if you did not have to use it to pay for your electricity?

The fact is that you can come off the grid and you can even sell your surplus, home-made electricity back to the grid. This is unlikely to make you a lot of money, but it is a nice feeling after only paying out for decades. However, the savings of life off the grid do not stop there. There are ecological savings and the saving of human life too.

Soldiers would not be sent to combat for oil if we were not so reliant on it. The fact is, that if more people came off the grid, the price of oil would fall, because demand would go down and the oil-producing countries that believe they have a strong hold on the West would lose their power. And that can not be a bad thing either, can it?

It is easiest for people who live in their own houses to come off the grid. They have more jurisdiction over their own property and can make their own decisions about what to do with it. Drill a hole here, cut a hole there - that sort of thing. Alterations or home improvements. Life off the grid is also most beneficial for families as they use the most electricity.

The most common ways of attaining a life off the grid is by the use of solar panels, hydropower and wind turbines or even good, old-fashioned wind mills. These devices are still expensive to buy and very expensive to have fitted. A recent study in the UK estimated that it would take 10 years to recover the investment of a professional installation of energy-making equipment.

However, you could remove the expensive labour element by making and installing the units yourself! This opportunity is accessible to anyone in the world as the diagrams and plans for making these units are available on the Internet from specialist alternative energy web sites and the components are practically every day items.

You will be able to obtain them from a hobbyist or DIY shop. They are also very easy to assemble - most teenagers could do it and so could you. If you do not like that way, you could purchase a self-assembly kit.

Once you have started to become free of the grid, you can make life off the grid even more rewarding by renewing your appliances, as and when necessary, with low energy models. If you approach life off the grid wisely, you could add new energy producing units every month until you do not get any electricity bills any more and then whatever further savings you can make will be sold back into the grid.

Climate Change Quicker Than Predicted

Wednesday, August 26th, 2009

An increasingly large amount of scientific research, published since the IPCC 4th Assessment Report was released in 2007, shows that climate change is occurring right now, and that it is much faster than predicted only two years ago.

The evidence for this statement is from a multitude of areas. Some of the regions currently undergoing change are shown below.

-Many physical systems, in widespread sites, are already showing evidence of global warming. Examples include the timing of plant flowering, animal breeding, and lake thawing.

-Increased ocean surface temperatures in Pacific & Atlantic hurricane-formation zones which will lead to stronger cyclones are definitely related to human-induced warming.

-Ocean acidification is occurring quickly, due to CO2 in massive amounts dissolving in salty water. This will have major impacts on marine ecosystems and subsequently food supplies for many countries.

-Expected sea-level elevation over the next few decades will be greater than that predicted in 2007. It will probably increase a metre or more, according to recently published research.

-The accelerated melting of the ice sheet in Greenland that started in 2004 has been definitely linked to climate change.

-The West Antarctic Ice Shelf has undergone rapid melting over the last 10 years and has suffered 10 major ice shelf collapses over that time.

-Northern polar sea-ice is melting much quicker than previously estimated, and it is likely that the Arctic will be free of ice in summer within a few decades.

-Permafrost in the Arctic Circle is thawing much quicker than recently thought, and is releasing larger amounts of greenhouse gases than predicted.

The global warming that is now occurring is going to extend for multiple centuries even after all human-released greenhouse gas escape ceases. This is due to the significant inertia that exists in the climate and the delayed decay of carbon dioxide from within the environment.
