How Effective Is Solar Power?

By Joshua Nicholls

The sun is the source of all our power. A statement not untrue, albeit a little misleading. The sun's radiation is the origin of all the power sources we use today, affecting chemical changes to create everything from nuclear power to the much greener wind power. But how do we harness the sun's energy, and how effective is it? A worthy question. After all, solar power is almost eternally available and, most importantly, free.

Applications
In theory, solar power can power everything on earth. In practice, it's a matter of logistics. Solar power is the conversion of sunlight to electricity through either converting it directly to photovoltaics (PV) or by concentrating solar power (CSP), using it to boil water into steam, which then generates electricity. Since the sun is only emitting radiation on any given point during daytime hours, and is affected by elements such as cloud cover, it needs to be combined with a method of energy storage. Solar power's potential is vast, and could easily supply all the energy in the world, hundreds of times over. However, the problem lies within the cost. Although the cost is coming down, solar power panels and plants are very expensive to produce.

How it works
The energy released from the sun is radiation - light and heat. This can be harnessed in two ways. Firstly, by using panels containing photovoltaics, which absorb the radiation and convert it into direct current energy. Photovoltaic devices are a type of photodiode, which means photons of light from the sun knock electrons within the device into higher states of excitement, thus generating electricity. The other method is by concentrating solar power by means of mirrors and lenses onto a point, which can then be used to heat up water, converting it to steam and then energy. Think of a kid using a magnifying glass on an ant colony, then magnify that heat (excuse the pun), and you can see what kind of energy can be produced.

Comparisons with other sources
Solar power is still behind fossil and nuclear power sources in terms of power generated, but its benefits for the environment far outweigh its polluting cousins. Water generation, although greener than fossil and nuclear, still requires dams and can alter landscapes dramatically. Wind power is comparable, in terms of a renewable energy source, but wind turbines can be loud, take more time to install, require maintenance and are more susceptible to weather damage.

Storing energy.
As an intermittent energy source, solar power must be stored if it isn't to be used immediately. In power plants, the energy is stored either as heat in a heat-retaining material or as pumped-storage hydroelectricity, meaning the energy is used to pump water from a lower reservoir to a higher one. In home-based solar power storage, the solution is usually a series of rechargeable batteries that can store the excess electricity.

Is it a realistic way of powering your home?
Many people use solar power in their homes as an alternate energy source, however it is usually combined with another source, such as wind or even the power grid. The effectiveness depends on both your location and is reliant on other sources. Ask an electrical services company for more information.

Solar power is being rapidly developed all around the world, being included in projects to create one hundred percent renewable energy plants that combine solar with wind, water and biomass power sources. It is an effective source of energy, but must be harnessed smartly and used in combination with other sources.

Energy Labelling for White Goods

By Ronald Jackson

Since 1995 all white goods sold within the EU must display an EU Energy Label which enables customers to see the energy efficiency and performance of every electrical appliance. When it comes to common household appliances it is true to say that consumers are being made and becoming more and more aware of the energy performance and factoring this into their searches when buying new.

Just as the traffic light labelling system on all food sold in UK supermarkets enables you to see the calorie, fat, saturates, sugars and salt content, so the EU energy labelling allows you to see the electricity and water consumption of every appliance before you buy so you can make an informed decision about the effect your purchase could have on the environment.

The energy labels were introduced as a way of making consumers more aware of the impact of the use of every day household goods on the environment and to encourage manufacturers to strive to create the most energy efficient appliances on the market. The labels have worked in both respects and people are now generally far more aware of the A to G ratings and what they indicate, specifics are still a little blurred but the point is that everyone can now easily work out that A rated home appliances are good and G rated appliances are not so good.

Not only is the energy labelling system a useful guide for manufacturers and consumers alike when marketing and buying products but they are also useful for carrying out quick repairs, whether you're talking about Hotpoint dishwasher repairs or Whirlpool fridge repairs, appliance engineers will do the quickest and most efficient job if they know as much about the product in question as possible. Investing in energy efficient products is a good idea, they will be manufactured to very high standards so not only should they have a longer lifespan but they should also improve the state of the environment which is really struggling, due in part to human activity.

Choose your new home appliances carefully, taking the energy rating into account but not using it as a sole reason to buy that particular product. By doing your research you will be more likely to choose a product which not only does what you need it to do but which will last as long as possible, meaning you are less likely to need appliance repairs but if you do, the better quality and better known the brand, the quicker and easier your Hotpoint dishwasher repairs and Whirlpool fridge repairs and the like should be.

Get online to find the cheapest, quickest and most cost effective Hotpoint dishwasher repairs and Whirlpool fridge repairs wherever you live in the UK.

How to Buy an Energy-Efficient Washing Machine

When buying a new washing machine, one huge factor to consider is the energy-efficiency of the washer. A typically washer gobbles up a lot on electricity when using the hot water cycle or the integrated dryer. Anything that involves producing heat can increase electricity consumption.

So, when you are buying, make sure you compare the efficiency of those machines when it comes to consumption of energy. Here are some tips that may prove to be beneficial:

1. Bring with you an Energy Guide yellow sticker. This will guide you on how to make the proper comparison when it comes to the consumed energy of the washer in terms of kilowatts per hour. Also, it will tell you a ballpark figure of how much it costs to operate the machine on an annual basis. This is the most accurate guide to comparing energy-efficient washing machine brands because it is released by no less than the US Department of Energy.

2. Consider saving up for a front load washer. There is a reason why a front loader is the cream of the crop in today's day and age and that is because this is a machine deliberately made to consume less water and energy. Thanks to its H-axis drum and the dispensed need to use an agitator, the clothes tumble instead of spun. As a result, the drum has more space for your clothes and you can use less water and detergent. It is definitely a more economical choice.

Does Eco Friendly Mean The End For The Tumble Dryer?

As Global Warming and Climate Change start to show us that they are indeed a real advent of our modern society, when do we get to a point and say, well some things just have to change!
Our kids demand of us we leave this planet in the best shape we can if they say so or not, its our own moral duty that can actually save us money when we go about it. Some key points that are discussed here revolve around the availability of environmentally friendly products that can be used to dry any amount of household washing.
The main environmental aspect of using these eco friendly products is that your homes eco foot print is minimised, as the CO2 emissions produced for powering tumble dryers are reduced or eliminated altogether.
One of the largest consumers of energy in the home is the electric or gas fired tumble dryer, and I often wonder how big a change could be made if everybody got behind the removal of these energy suckers from the planet.
This also has a flow-on effect in the home as your electric and energy bills are reduced, your clothing smells better plus lasts longer, and you have more money in your back pocket to spend how you please, not just pour into ever increasing utility bills.
Right at your very feet in your local hardware or on the net, you will find a selection of eco friendly products to dry clothes in all sorts of situations.
