Why the temperatures in the solar wind are almost the same in certain directions, and why different energy densities are practically identical, was until now not clear. With a new approach to calculating instability criteria for plasmas, researchers have solved both problems at once. They were the first to incorporate the effects of collisions of [...]
Engineers are developing a solar panel composed of nano-antennas instead of silicon semiconductors. They say that through the use of these antennas, a much higher conversion rate from light into usable energy can be achieved — and could lead to a more cost-effective way to harvest and utilize “green” energy.

In a step toward engineering ever-smaller electronic devices, scientists have assembled nanoscale pairings of particles that show promise as miniaturized power sources. Composed of light-absorbing, colloidal quantum dots linked to carbon-based fullerene nanoparticles, these tiny two-particle systems can convert light to electricity in a precisely controlled way.

With current investment products such as pensions, ISA’s and saving accounts giving such a low return, investors are looking for other ways to increase their savings. One way to do this is by investing in Solar panels. Solar panels are a great way to help the environment, generate income, and reduce your electricity bill. How [...]
Ever tought of Solar energy for cars?Solar energy is one of the many renewable sources of energy that is used for fueling vehicles, running consumer products and for the efficient running of homes and business establishments.The solar Cells will run the equipment. The future vision that we have is to power all cars with solar [...]
How can we do that. How can we achieve such thing? Yes, we can achieve that if we are smart enough to apply certain ways that can reduce the cost. One of the suggestion, is to use thin layer solar cells to get a much more cheaper from green technology. We all agree that solar [...]
Lets get to the bottom of solar energy, for some new readers that needs a strong start about solar energy. today i am going to concentrate on explaining the basic of solar energy. First and foremost, the energy that we are going to talk about is coming from one source only, which is the sun. [...]
Advantages of Solar Energy After initial investment, all the electricity you produce is free and incentives and rebates from governments and utility companies offset the initial investment new financing vehicles such as leasing and Pace offset the initial investment while preserving the incentives and rebates. Net metering gives you the opportunity of selling your excess [...]
It’s just a question of finding a big enough area for enough 1% efficient cells to generate the energy we need. Solar electric power modules are continually improving in efficiency, with PV modules once at 4-6% now pushing up into the teens, and some large-scale solar thermal installations going considerably higher. Asking the efficiency question [...]
Pros of Solar Energy Unlike nuclear energy and energy obtained from fossil fuels it does not leave behind waste products and is a non-polluting source of energy. It doesn’t have the dangers of nuclear technology. It reduces mankind’s reliance on fossil fuels. While the known fossil fuel reserves are expected to be finished in the [...]
Photovoltaic panels take quite a lot of energy to manufacture. Some experts believe that it can take up to 11 years until the energy produced by a photovoltaic panel equals the amount of energy used to make it. However, most people wanting to install photovoltaic panels intend to use them for longer than this. And [...]
Solar energy can be used for electricity, central heating, hot water, cooking, for producing salt and even for desalination. Solar energy comes from the sun’s rays. Solar energy is very environmentally friendly. However, when the sun rays enter the earth’s atmosphere it is quite dilute. While solar energy is considered to be a very environmentally [...]
PRO Financial incentives (USA, Canada, European states…) can reduce the cost of the initial investment in solar technologies. The U.S. government, for instance, offers tax credits for solar systems certified by by the SRCC (Solar Rating and Certification Corporation), which amount to 30 percent of the investment (2009-2016 period). Heating our homes with oil or [...]
* Solar Energy is clean, renewable (unlike gas, oil and coal) and sustainable, helping to protect our environment. * It does not pollute our air by releasing carbon dioxide, nitrogen oxide, sulphur dioxide or mercury into the atmosphere like many traditional forms of electrical generation does. * Therefore Solar Energy does not contribute to global [...]
Disadvantages of solar energy mainly come from the initial cost of the equipment itself to be form. To used to harness the suns energy needed new technology equipment. Solar energy technologies still remain a costly alternative means expensive to the use of readily available fossil fuel technologies. As the price of solar panels decreases, mostly [...]
Solar Energy Is more than enough Solar energy is more than enough because it’s around us all the time without any doubt is everywhere. It’s abundant and we’ll practically never going to finish using it. We include also in mid winter, we are still blessed with a moderate amount of natural daylight provided courtesy of [...]
Solar energy: Solar energy is the energy which the sun produces in the form of solar radiation. Through the use of solar panels or solar cells, the photons in the solar radiation are converted into electricity. However one disadvantage going with this form of energy is the high prices of solar panels. Large numbers of [...]
Costly Equipments Integrating a solar energy system into a society is a very costly affair for a government and if it happens to be a developing country, one can easily forget solar energy. Governments are not ready to give up the infrastructure they already created for fossil fuel technologies and will not easily take up [...]
In these vehicles “photovoltaic cells” are used which directly convert solar power into solar electricity. PV cells directly convert sunlight into electricity. When sunlight strikes PV cells, they excite electrons and allow them to flow, creating an electrical current. PV cells are made of semiconductor materials such as silicon and alloys of indium, gallium and [...]
Who said having a solar energy does not create problem. Everything in this world have pros and cons. Here we going to talk about the burden of having Solar energy at our house. First and foremost, everyone really hates to throw cash on solar energy because it cost expensive with it’s equipment. Let me give [...]
Renewable Energy and Data Centers
As organizations like Greenpeace pressure Internet companies to use more energy from renewable sources, data center operators are struggling with the best approach to renewable power. To get some perspective on the issue, we spoke with John Stanley, a researcher at The 451 Group who specializes in “Eco-Efficient IT” and the intersection between data centers [...]
Switching on India’s solar future
India is confronted with the triple challenges of climate change, energy security and economic development with political will and technological prowess. But will that be enough to bring in the capital it needs to ensure a transition to green growth? India already has a head start in the race for renewables, ranking fifth in the [...]
Melaka invested RM3.2 million in a solar energy plant.
KUALA LUMPUR: Melaka will be declared a “developed state” come Oct 20 by Prime Minister Datuk Seri Najib Tun Razak. The declaration will be done via “online” from Kuala Lumpur, said Melaka Chief Minister, Datuk Seri Ali Rustam. The quest to get developed status for the state under a 10-year plan known as Melaka Maju [...]
