In addition to solar energy and wind energy, geothermal energy is one of the most unexplored sources of Green Energy. However, with development in technology it would become possible in near future to benefit from this free source of energy.

Geothermal energy is the heat generated in the earths crust. This is a Green Energy source that is both sustainable and clean. The resources of this form of energy include ground hot water or hot rocks found at a depth below the Earths surface. The source of the energy originated in the red hot magma present several kilometers below the surface.

Tapping Geothermal Energy

Throughout the Earths surface, the shallow ground maintains an almost consistence temperature that ranges between 50F and 60F. Geothermal heat pumps are designed for tapping this source of Green Energy for both heating and cooling buildings. This system comprises of the following components:

Heat pump
Heat exchanger
Air delivery system

The heat exchanger comprises of a network of pipes that are buried below the shallow surface close to the building.

During the winters, the heat pump takes the heat away from the heat exchanges to pump it to the air delivery system. And, during the summer season, an opposite process takes place. The heat pump takes heat from the air delivery system and transfers it to the heat exchanger. In addition, this heat removed from the indoor can also be used for heating water.

Generating Electricity

Electricity can be generated from this Green Energy source by drilling wells into the underground hot water reservoirs. Some of the power plants utilize the steam emitted from the reservoirs for running turbines or generators. And, some plants make use of the hot water for boiling a fluid to vaporize it and to turn a turbine.

If hot water is available at the surface, the heat provided by it can be used directly. The range of direct applications of this Green Energy source include:

Heating water in fish farms
Heating buildings
Nourishing plants in greenhouses
Industrial procedures like pasteurizing milk
Drying crops

Use of Hot Rock Resources

Hot rocks are found at depths between 3 and 5 miles below the surface of earth. The good thing is that these hot rocks can be found almost everywhere on the planet. This resource can be tapped in an area by dropping water into one well, allowing it to circulate through the hot rocks and then pulling the hot water out from another well. Geothermal energy is currently not being used for any commercial purposes. In addition, the current technology doesn’t allow extracting heat from the hot molten magma which is a huge resource of sustainable Green Energy.

Humans have recognized and utilized the power of the sun for a long long time, but it is only in the last thirty years or so that solar energy has come to the forefront of the energy revolution. Now recognized as a totally viable source of energy across the globe, solar panels are big business. Whether powering huge industrial buildings or a humble two-up two-down residential property, solar panels take power directly from the sun to eliminate the need for the sourcing of energy from non-renewable sources. We all know that solar energy is a great solution to our energy needs going forward, but there are plenty of things most of us don’t know about this wonderful source of energy.

Solar Panel Price Drop

Although solar panels are becoming more popular, they still only make up a fraction of the generated energy in the world, with most energy still being sourced from fossil fuels. Thankfully, the price of having solar panels fitted has dropped dramatically over the last few years, so we can expect the trend to change dramatically in the future. In many European countries, including Britain, energy created from the use of solar panels can be sold back to the national grid. This, of course, means that owners of panels can earn an income from their panels, while generating free energy for themselves.

Solar Power

Solar panels have huge power. If the Sahara Desert were completely covered in solar panels, this dry, hot, and particularly sunny part of the world would generate enough energy to power everything in the whole world for 30 years! Just a kilowatt of solar energy also allows you to effectively avoid creating 300lbs of carbon through the use of normal energy sources. Carbon is the element which is said to cause the greenhouse effect. Energy experts have also surmised that if everyone the world over changed to using solar power, enough power would be created to fuel the world 5,000 times.

Creative Energy

Leonardo da Vinci is credited as being the first person to harness the power of the sun to effectively create solar panels. He successfully boiled water by reflecting rays of sunshine against concave mirrors. More recently, photovoltaic technology was first developed in America, but surprisingly, their limited use of the energy source accounts for just 6% of the world’s solar energy use. Surprisingly, Germany, with a fairly poor sunshine record, is known for being the largest producer of solar energy in the world.

Solar Effective

Solar power is the most effective form of energy in terms of actual yield, creating more than both fossil fuel and nuclear power. This is, of course, a massively important fact, and one that should persuade us all that it’s an extremely good and responsible idea to investigate the possibility of using solar power if it’s at all possible for us to do so. The cost of having solar panels is still high, but most people find that they make their money back in the long run. When you consider that solar power is the best thing for the environment and the best thing for your pocket, it should only be a matter of time before everyone is changing.

When the weather is warm we tend to spend time in our yards mowing the lawns, trimming the bushes, planting flowers. We all have a desire to want the outside of our houses look nice. Whereas this is often a worthy cause, are we putting as much diligence into making the outside of our homes cost efficient? We work hard to keep a roof over our heads thus why toss money away by permitting heat to escape?

The majority of the houses heat escapes in the course of drafts. Filling these drafts will save on the heating cost over time. Do a walkthrough around the exterior of you home to find what has to be improved. First you should examine all the areas where two different construction materials meet for example where the siding meets the chimney and where the foundation meets the exterior brick or siding. Examine all exterior corners as well. Youll need to fill any cracks or openings in the mortar, the foundation or the siding. Make sure to fill them with the suitable substance. If you are going to complete a job, do it right. And, it can last longer if its done the proper way with the correct material. You will also want to inspect where faucets or pipes extend from the exterior. Make certain there are not any holes around them as well. In your exterior inspection, dont miss the windows and doors. Make sure that theyre all properly caulked and that windows and doors seal tightly. Some people have air conditioners mounted directly into the wall rather than in a window throughout the summer months. While this might save on time of installing and un-installing the air conditioner each year, it is also a great way to let in drafts throughout the winter months. Make certain that the area round the air conditioner is properly sealed. If you dont have one by now, invest in a cover that may be placed over the unit in the winter. This can stop the unwanted cold air from getting in your home.

Also, make sure that your house is properly insulated. This will save you a large amount of money. In particular check the attic. Make certain that there is a steam barrier under the attic insulation. Water vapor will pass through the ceiling. With large amounts of moisture, the effectiveness of your insulation goes down and may cause structural damage. In order to prevent this, you should have a vapor barrier which may be tarpaper, Kraft paper attached to fiberglass batts, a plastic sheet or vapor barrier paint. Additionally make sure that any gaps round the pipes, ductwork or chimney is correctly sealed.

If youve got the funds, you might need to consider replacing recent doors or windows with new energy efficient ones. While this can be an improvement that will dip into your pocket, it will as well save you cash on heating. With the price of home heating, making sure that the exterior of your home is properly sealed is almost a necessity.

Environmental factors come into play when it comes to choosing the right replacement windows for Houston homes. The National Fenestration Council has a rating system that measures and compares the energy performance of windows. If youre in the process of choosing replacement windows in Houston and youre not sure what to ask your contractor, here are the numbers that you should look out for.

1. U-Factor
U-Factor indicates how fast a window assembly releases heat. The lower the U-Factor, the better the windows can help to insulate your home. Although the areas climate is usually warm, replacement windows in Houston are still recommended to have a low U-Factor in the event of cold winters. U-Factor rating is from .20 to 1.20.

2. Solar Heat Gain Coefficient
Solar Heat Gain Coefficient determines the amount of heat from the sun that the window is able to block. The measurement is from 0 to 1. Lower SHGC means less solar heat entering through a window. This is a particularly useful rating to take note of for replacement windows in Houston as can get really hot during the summers.

3. Visible Transmittance
Visible Transmittance gauges the amount of light that enters through a window. To let more natural light into your house, opt for a window with a higher rating on a 0-1 scale. Higher visible transmittance for replacement windows in Houston can help you save more energy. Instead of leaving lights on, take advantage of natural light by having it brighten your home.

4. Air Leakage
Since heat loss and gain are affected by the cracks in the window installation, the Air Leakage rating measures the amount of air that goes through the assembly. You will want windows that have a rating of .3 or less. This is an important aspect for replacement windows in Houston when keeping your air conditioning on during the summers.

5. Condensation Resistance.
The rating for Condensation Resistance is from 1 to 100. The higher the number, the better the window is at resisting condensation from forming on its inside surface. Since Houston’s climate can be both hot and humid, having replacement windows in Houston that can resist condensation is a must.

Choosing energy efficient replacement windows for Houston homes is important if you’re planning on saving money. The National Fenestration Council’s rating system doesn’t just take into account the materials that you use, but also how the replacement windows are assembled. This is why a replacement windows project is better off left to a professional. You will want to make sure that your replacement windows are properly assembled. It will save you a lot of money in the long run.

When social tariffs were first proposed, they were not seen as being fair to everyone. The idea was to combat excess winter deaths by helping UK residents that were at risk of fuel poverty to pay their bills with a discounted rate. However, that discount would be heaped on the backs of wealthier customers who would then make up the difference. The effect was to be temporary as the Green Deal would then help more and more UK residents to adopt green technologies that would reduce the overall energy demands of the country via grants and other types of financial assistance. Now that the social energy tariffs are being replaced by the Warm Home Discount, the same question arises with respect to the most vulnerable groups in the UK. Is it fair to get rid of social tariffs that the broader group needs to keep heating their homes?

Low Income Group Has Green Options

The UKs energy strategy continues to evolve as it seeks to reduce its dependence on outside energy sources while maintaining social protections in place for its more vulnerable citizens. The social tariffs were never meant to be a permanent fixture, as the policy outline in 2009 indicated that the effect would be temporary based on the implementation of the Green Deal technologies. For that reason, numerous schemes were put in place to help low-income citizens improve the draughty homes so typical of Britain using insulation, window-glazing, and other services. Many of these services were provided for free to qualifying low-income households. Also, those who could afford to implement these technologies and pay for them were also helped to find ways to achieve these goals. None of these energy schemes are expected to last forever, however, and even the Warm Home Discount is to expire in March 2015.

Keep An Eye On Excess Winter Deaths

There is data to indicate that the social energy tariffs, along with other grants and energy improvement schemes, have helped to reduce the excess winter death rate in the UK. While there were 24,000 excess winter deaths for the winter of 2011/2012 in England and Wales, that figure represents an 8 per cent drop from the previous winter. The social tariffs are being slowly phased out, with many of them being replaced by the Warm Home Discount for the 2013/2014 winter seasons. Even though no one can tell how much warmer home are in the UK, if the schemes have done their job and the Warm Home Discount is doing a fair job of it, then this number should continue to decrease. If it goes up, it will be a huge indicator that more changes need to be made to the UK energy strategy, not just to make it fair, to avoid killing more residents.

Fair Deals Change With Government

A question of fairness is always going to be an issue with social reforms. However, political parties tend to see fairness in their own terms. This does lead to changes in how schemes are planned and implemented, or whether they are eliminated altogether. Some would suggest that the Winter Fuel Payment changes are unfair to expatriates who live in countries deemed “warmer than the UK” even though the winters may be equally harsh. These UK residents will no longer be eligible and may suffer undue hardship. However, with the change of government, comes a change in the ideals of fairness. The new government believes that it is not fair to continue to pay for heat subsidies that are going to people who arent even in as drastic a need of them as others. As policies change, so do social tariffs, with the eye towards creating reforms that hit realistic targets and that do good in the community of people it is meant to serve. None are meant to be permanent, nor are they meant to require no further changes once they are implemented. As the UK faces the harsh winter ahead, social tariffs may be a thing of the past, but the ideal to create a fair society where even the most vulnerable have a chance at being able to pay their bills has not. It is merely changing and adapting towards newer social reforms that meet the needs of the population as a whole.
