What Makes Geothermal Energy Green ?

What makes Geothermal Energy greenThe total power demand from different areas of the world comes from various energy sources. Some countries mostly depend on hydroelectric power, while others depend on nuclear power plants. However, with the increasing demand for energy, other sources have  had to be developed. These include geothermal energy sources. For several decades, geothermal energy has received the award as the cleanest renewable energy source used in the world today. Since it is proven to be environment friendly, many environmentalists promote the use of geothermal energy sources. But have you ever wondered what makes geothermal energy green? This question will be answered in just a short while.

What makes geothermal energy green?
Geothermal energy is the form of energy which comes from the core of the Earth. The warmth and heat from the core is generally produced by radioactive decay. According to experts, the amount of geothermal energy present in the Earth’s surface and core is enough to supply the energy needs of the entire world. However, due to lack of resources, not all countries can have geothermal power plants.

The main reason in what makes geothermal energy green, lies in its production and conversion of energy to electric power. This process does not lead to the emission of toxic chemicals to the environment. It may release some chemicals such as carbon dioxide but compared to other energy sources, its emission is relatively low. Geothermal energy does not provide poisonous chemicals to the air as its emission is within normal levels.

Another consideration in what makes geothermal energy green is that it does not cause destruction to land and water. The water used during the production of geothermal energy sources is introduced back to the earth without being contaminated. Geothermal power plants do not emit toxic fluids that can be absorbed by the land or can flow to water supplies. Unlike nuclear energy sources, geothermal power plants will not cause severe problems to its surrounding natural resources since it does not emit radiation.

A further reason to consider in what makes geothermal energy green is it can be produced easily without the need of expensive infrastructure. Huge machineries usually emit toxic gases especially if they are run by crude oil and other types of fuel. Aside from using it for pumps, geothermal energy production does not require any form of fuel. The transportation of geothermal energy sources has also been made easier. Energy sources can be conserved and used for other purposes when you choose to use geothermal energy.

Sustainable and renewable energy sources such as geothermal power plants are generally considered as safe and “green” since they do not cause damages to the environment. They are healthy not only to the air, land and water but also to living creatures such as plants, animals and human beings.This is probably the main consideration in what makes geothermal energy green.

With all these advantages, you should first consider “green” energy sources for your electric power needs. Many electric power companies offer energy from geothermal sources. To know more on how to get green energy source, you can visit their official websites.

Wind Energy for the Home ; How does It work?

Wind

Home Wind Energy

Wind energy is one of the best forms of energy that you can take advantage of to power your home. This energy is achieved from wind turbines, windmills, and other forms of technology. However, it is common for homeowners to use mainly wind turbines. Wind energy can create energy that is not only lowering  your power bill, but is also helping out the environment. This form of energy has always been considered just as powerful as solar panels, but the difficulty is in creating the turbines and placing them on your property.

How does wind energy work?

When a wind turbine  is designed and put in the backyard or on your roof, it is going to be connected to your generator that makes everything in your home work. Once it is connected, the  turbine will be utilizing  the available wind, 24/7,to create energy that your home can start using. The faster the  turbine spins, the more energy your home is generating. Solar panels rely on the sun shining to give energy while turbines rely on the air currents found in the air. This form of  energy isl very powerful as long as a consistent amount of wind is experienced in your area to generate the power.

How to build wind energy machines

The way to build a wind energy machine requires a lot of work. You mainly want to buy a motor or generator, and then several tools like batteries and a control system. You can buy a lot of great systems online with the turbine half built.

Concentrated Solar Power. IBM launch new breakthrough system

Concentrated Solar PowerIBM scientists in Zurich  today announced a breakthrough in concentrated solar power technology that promises 80% efficiency and that will be 3 times cheaper than existing systems.

The High Concentration PhotoVoltaic Thermal (HCPVT) system developed by the IBM Research  laboratory uses a mirrored, parabolic dish to direct solar energy onto a series of 1 cm square photo-voltaic cells.A tracking system ensures the dish is always directly aligned with the sun as it moves across the sky, enabling it to concentrate the equivalent power of 2,000 suns.

Combined with a revolutionary new cooling system,already used in IBM’s super computers,which is 10 times more effective,this new concentrated solar power technology supplies 30% of the collected solar radiation as electricity with an additional 50 per cent being captured as heat which can be used for water desalination as well as air conditioning.

IBM Research scientists believe that the revolutionary design incorporating lightweight but high strength concrete as well as inexpensive pneumatic mirrors, will help them achieve a cost per aperture area below $250 per square metre -instead of the $750 cost of comparable concentrated solar power systems.

The cost effectiveness, efficiency, and additional applications make this concentrated solar power technology a good fit for southern Europe, Africa, the Arabic peninsula,the southern United States as well as South America, and Australia, IBM Research strongly believe.

They also argue that the technology would be suitable for remote locations, such as the Maldives, Seychelles and Mauritius.

Andrea Pedretti, chief technology officer at solar company Airlight Energy, which is working with IBM and Swiss academics to develop the system, said these regions might also see a jobs boost as a result.

“The small high-tech components, in particular the microchannel coolers and the moulds, can be manufactured in Switzerland with the remaining construction and assembly done in the region of the installation,” he said. “This leads to a win-win situation where the concentrated solar power system is cost-competitive and jobs are created in both regions.”

Renewable Energy.Strong future predicted up until 2030

Renewable  EnergyAnalysts from Bloomberg New Energy Finanace,now predict that renewable energy will account for up to 74 per cent of all new power capacity added by 2030 worldwide, despite the current market downturn.

Annual investment in renewable energy technologies, such as wind and solar power, is likely to soar some 230 per cent by 2030 they believe as the industry across the board drives down costs and starts the widespread  uptake of base load green technologies, such as biofuels.

The BNEF report shows investment in new renewable energy assets will reach $630bn a year by 2030, more than triple the investment seen by the industry in 2012 and bring total installed capacity to 3500 GW,more  25% than previously predicted.

These  upbeat predictions are based on growing evidence that core renewable energy technologies are seeing costs fall at such a rapid rate that they will be soon be at parity with fossil fuel produced electricity.

BNEF’s analysis predicts wind will account for 30 per cent of new capacity by 2030 and solar at 24 per cent . Worldwide biofuel production meanwhile, is predicted to increase by around 200 per cent reaching some 370bn litres by 2030.

With large hydro projects also being taken into account, BNEF believes renewable energy may well account for between 69 per cent and 74 per cent of all new global electricity generation capacity added by 2030.

Guy Turner, for BNEF, said the report highlights the strong potential for continued growth in global renewable energy markets, despite a downturn in clean energy investment since 2011.

“Renewable technologies will form the anchor of new generating capacity additions, even under a less optimistic view of the world economy and policy choices,” he said in a statement.

“The main driver for future growth of the renewable energy sector over this time frame is a shift from policy support to falling costs and natural demand. Our work also highlights, however, the importance of planning for the integration of intermittent renewables into the grid and into power markets. This will require significant new investment in grid infrastructure, load management and storage technologies.”

Solar News : Latest Stories from around the UK

Solar NewsUK Car Manufacturers driving Solar Energy agenda forward.

World famous, iconic car maker Bentley has just finished the installation of what is believed to be the UK’s largest rooftop solar PV system. Some 20,000 panels,now cover the 3.45 hectares of roof space at Bentley Motor’s UK factory in Crewe with a combined  capacity of 5MW,which it is hoped will supply up to 40% of the plant’s peak time energy needs as well as reducing it’s CO2 emissions by 2500 tonnes a year.

Excess electricity,produced at weekends and during factory holiday periods is fed back to the National Grid.Although built 70 years ago, the saw tooth design of the Crewe factory’s roof is ideal for solar energy production due to it’s  20 degree south facing slope.A company spokesman added ”The solar panels will reduce our energy costs and help ensure that our manufacturing operations in Crewe are efficient, sustainable and globally competitive.

Not very far away from Crewe,lies Toyota’s main UK plant at Burnaston in Derbyshire.Toyota have long been at the forefront of green issues and sustainability and their UK plant is no exception. The Japanese car maker sees the factory as one of it’s “eco plants” and a showcase for green technologies.It currently houses the largest direct factory-connected solar PV array in the UK.Currently,some 16800 panels are producing up to 40% of the factory’s energy needs. Other innovative additions include a 103 square metre solar glass wall, a ‘brise soleil’ sunshade of panels above the windows, and a solar canopy that charges the site’s electric tour train, which feeds into the plant when not in use.

New Dorset Solar Farm

British Solar Renewables, has announced a new solar farm for Dorset.The company has now received planning consent for a new 20MW facility to built close to Bournemouth Airport.The site is next to an existing recycling facility and a company spokesperson reported that the project was designed to complement other environmental management measures at the site.Work is expected to start shortly at the 120 acre  site and they expect to be exporting power to the Grid by late summer.

Surge in Solar Parks Continues

More evidence of the increasing popularity of solar energy was reported this week.Trina Solar has successfully completed delivery of 137,000 panels  for the new 33MW farm at the former RAF Wymeswold airfield.The modules were installed and connected to the grid before the end of last month, thereby beating the deadline for cuts to the Renewable Obligation support mechanism.

Elsewhere,TGC Renewables have lodged a planning application for a new 4.5MW solar farm in Somerset. The proposed site on farmland nr the village of Oake, would house 16o00 panels and provide power for 1000 homes and is another example of the trend in farming towards diversification.A company spokesperson stated”As the UK farming community starts to recognize the returns that they can secure through providing lower grade agricultural land for green energy developments, we have a growing pipeline of UK projects that provide clean electricity and power to the National Grid.”

Saving Energy: 10 Top Tips for your Home

Saving EnergyEnergy bills are soaring and family budgets are being squeezed the world over. Saving energy has never been more important to every family. The average home uses power hungry appliances and inefficient lighting and heating systems. Below we list our top 10 tips in reducing your energy consumption and thereby saving energy use and cutting those massive bills.

 

Saving Energy by Reducing Your Energy Needs.

The best solution to saving energy is to change your bad habits and look at the inefficiencies in your current systems that are contributing massively to your electricity costs.   Consider all of the below points and you will make a noticeable difference in saving energy use around your home.

1. Get out of the habit of leaving lights on when not in use and more importantly replace all of your lighting with energy efficient led or fluorescent bulbs. This simple move alone can cut electricity use for lighting by 50%.

2. Stop being idleAlways switch off and unplug your appliances. Never use the standby function. This wastes too much energy. It is now possible to buy energy saving gadgets which will do this for you, but break that  bad habit and make it part of your daily routine and you will be saving energy.

3.Older,inefficient and power hungry appliances, like your cooker, washer or fridge/freezer, although there is an upfront cost involved, should be replaced with modern energy efficient models .This move alone can cut your entire energy bill by 30% This in itself makes a major contribution to saving energy.

4. Try cooking meals, using a pressure cooker. The food tastes better and they use much less power. While you’re at it, why not cook extra, Cook once and eat twice should be your motto. Or even cook  for the whole week at the same time. Then you really are saving energy.

5 Consider your current water heating. That inefficient electric hot water storage system can easily be replaced by a modern tank less heater, which only heats the water on demand. Further savings can be made by installing the same type of shower in the bathroom as well. Lowering the water heater thermostat from 140 degrees to 120 degrees will also result in a 10% reduction in energy used.

6. Americans especially, love their air conditioning, but modern day heat exchangers are more efficient and make a real contribution to saving energy.

7. Ensure that the timer/ programmer on your heating only operates when the house is occupied and turn down both room and radiator thermostats at least one degree. You really will not notice the difference except in the amount of energy used. This alone can save 10% of your heating costs.

8 Wherever possible, use the cold or warm water cycle on your washing machine. Some 90% of the energy used on a single hot wash is wasted heating up the water. Modern day detergents will still give you the same wash standards on a cold wash.

9 Don’t be afraid of using your dishwater. Used correctly, it is more energy efficient than manual washing up. Always wash a full load at the lowest heat setting possible, but don’t rinse and let the dishes dry naturally. Invest in a Energy Star Rated model as these use at least 40% less energy.

10 Home insulation is an important, but often ignored factor in saving energy in your home. Double glazing and cavity wall insulation are the biggest savers of course but your loft should be fully insulated to at least a depth of 6 inches, and don’t forget weather stripping around doors and windows to reduce draughts. Implementing these measures can reduce your heating bills by at least 50%.

Implement all or any combination of these top tips and you will certainly be well on the way to saving energy in your home and seeing those electricity bills tumble. A further consideration for you to consider, while not directly an energy saver in itself, is to install your own renewable energy system.

Installing solar panels or a wind generator, is not only “greener” and obviously less polluting, but with the introduction of net metering around the world, they can even earn you money, by selling back any excess electricity produced to the utility company.
