Geothermal power plant uses geothermal energy to generate power and electricity. This is a natural energy source and is also a form of renewable energy which is also environmentally friendly. Geothermal power plants are usually setup at geothermal hot spots around the world. In order to harness energy, deep holes are drilled into the earth, until a geothermal source is reached. A pipe is then inserted into the hole which allows steam from the geothermal hotspot from within the earth to rise up to the earth’s surface. The steam is then forced into turbine which is connected to a generator, the pressurized steam begins to move the turbine which helps the generator to produce electricity.

This is a renewable source of energy . the earth’s crust lies on a sea of molten rock which produces tremendous amounts of heat. Cold water is then pumped down into another pipe which is then heated and converted into steam by the earth which is then sent back up the first pipe. The central problems with such a process is firstly , if too much cold water is pumped into the earth, this would cool down the geothermal hotspot. Read the full story

Solar energy prices from last 10 to 15 years had declined an average of 4% per year. A lot of progress has been made for increasing the cell’s efficiency, and manufacturing economies of scale are the underlying drivers of this price decrease. The figures in the Solarbuzz Global Price survey clearly show that prices had declined consistently over the last two years.

A solar energy system for home usually cost around $8-10 per Watt. If the government incentive programs exist and coupled with lower prices, secured through volume purchases then installed costs for solar panels can become as low as $3-4 watt, means that 10-12 cents per kilowatt hour can be achieved. If there is no incentive programs then solar energy costs range between 22-40 cents/kWh for very large PV systems. Read the full story

Solar Panels is a great tool that effectively collect power from sun. Day by day, people are more concerned to buy solar panels for their personal use. Solar Panels or the PhotoVoltaic Cells are mostly purchased for home purposes, since it is better to generate electricity than to spend money on buying electricity from power company. Anyhow, solar panels have some pros and cons attached to it. It is briefly described below:

Pros of Solar Panel:

• Solar panels saves money, the money you spend on buying electricity from power company can be generated at home. It is observed that many solar panels owners save much money then its original costs with the use of solar panels.
• Solar panels lessen your dependence on power company. You get electricity as long as sun is out there.
• Solar energy is far better than coal or nuclear power. It is clean, renewable and cause no harm to environment. Read the full story

These days, it is hard to find anyone who does not know about solar panels. Practically solar power is mostly used in remote areas away from national grid, but it is now becoming very popular in rural and sub-urban areas as well. Solar technology is progressing by leaps and bounds. It’s getting better and better each day.In following few paragraphs we have reviewed some latest advancement in this field:

1 – MIT Researchers Print a Solar Cell on Paper

The idea of clean and green fuel is great but it has certain disadvantages. First it’s so much expensive, second their power conversion rate is quite low. Final disadvantage is that you need storage space to save all the power, which is converted by a clean and green technology. The MIT researchers had developed solar cells printed on paper. This technology will take years to be in market for commercial use, but it is an interesting development.

2 – Solar Greenhouse to Produce Food and Electricity

It seems amazing that a greenhouse produce solar power and food. This unique has been done in Italy. Renewable energy companies Solar ReFeel, CeRSAA and solar panel manufacturer Solyndra are the companies are responsible for this project. This solar power greenhouse is being built at CeRSAA’s Albenga, Italy. Basic purpose of this project is to attain production of both food and electricity. The research team is also experimenting to validate the crop growth benefits of Solyndra’s technology by taking help of independent testing by a leading agricultural institution.

Solar power does not have to be restricted to new constructions only. Solar installation can be fitted in existing buildings to make the home run on solar power.

This means that a house that is connected to the power grid can take advantage of getting a back up too. On sunny days, the solar system can produce more energy than required, forcing your electric meter to run backwards. However, in order to do this, you must take into consideration the following points.

1. Consult a solar installer to discuss the various options of installing solar panels in your house. There is a great deal of technical work involved in fixing solar panels in houses that are already running on grid electricity.

Almost in every home there is a refrigerator. The refrigerators which we are having at homes are more cost effective, efficient and they are having long life also. But the refrigerators that we use in home run on electricity. That’s why those refrigerators don’t work if we live in area where there is no electricity or go for camping. For such type of conditions there are other types of refrigerators which are called gas powered refrigerators. Gas powered refrigerators works on the places where electricity is not available.

How Gas Refrigerators Work?

Gas powered refrigerator’s basic components are same like the electric refrigerators such as:

• Generator
• Separator
• Condenser
• Evaporator
• Absorber

These components work together, uses the gas as both fuel and coolant to make the refrigerator work when there is no electricity available. The whole process is effective, as its less energy efficient than the standard refrigerator. But it works effectively. Read the full story

Solar cells can be used to directly convert sunlight into electricity, making the home owners more energy independent. Most commonly, solar cells in homes are used through the installation of solar panels.

Solar panels can collect sunlight during the day and transform it into energy. The stored energy can be used to supply power to the home by heating water and producing electricity. Although installing the solar panels can be simple, but it can be physically demanding.

1. First of all, you need to purchase a solar panel mounting kit. Usually, kits contain the same types of materials, such as solar panels, mounts, hardware, an inverter, and a voltage gauge. You can purchase the kits at any home improvement store.
