In this article we will discuss some themes related to different types of constructions used to produce solar power. We will begin from the grid-tied systems. A utility-interactive solar power system makes electricity, which is put directly to the grid. The word grid-tied means, that the system is tied, verbatim, to the grid. This system will accumulate the energy even …

For last several decades the world climate has been changing faster and faster. For last fifty years average temperature of surface in the world has increased more than on 0.7 degrees Celsius. This caused such phenomena as, for instance, decreasing of Arctic Ice` amounts on 2.7% every decade. In the end of 20th century, beginning of 21st, the highest temperatures …

One of the most popular Hybrid cars on the market today is the Toyota Prius. It is both compact and economical, with a starting price of just $22,400. The price puts the Prius within the realms of possibility for the everyday, although environmentally-conscious, individual. The third generation of Toyota Prius, the 2010 model, has EPA ratings of 51 mpg in …

But along comes a company to my attention of late that seems to be proving that wrong. Clear Edge Power is advertising a fuel cells power system for home and business use now, not next year or beyond.

What is Net Metering? Coming from Nth Degree Solar Energy from Grand Junction Colorado, I get asked a lot about net metering, and how it operates, so here are some concepts to ponder about net metering and solar power generation. When you use electrical power, it spins your electric meter forward. You pay on this meter based on how many …

In December 2004, a UNECA sponsored study conducted by CEMMATS Aggroup Ltd., a local consulting firm, involved various stakeholders in the sector to formulate an energy policy. The CEMMAT’s energy agenda for Sierra Leone in terms of policy and management represents an significant set of instruments that fundamentally encapsulates a multi-disciplinary structure bringing together sectors of the energy community – …

Economics 101, Environmental Studies 101 and Technical Science 101, should be necessary classes for everyone to study because Economics and Technology are necessary to care for the Environment and Save the Planet. For those who may not be the university sorts or are well educated and shy away from any of these particular subjects, don�t be troubled. We’re talking about …

Reprinted from http://nthdegreeenergy.com/colorado-solar-projects-abound/ Colorado is a mecca for grid tied Solar Energy Solutions, due to a combination of high sun hours and large consumers of electricity. “Denver has more sun days then San Diego,” says Richard McCracken, owner of Nth Degree Solar Energy Solutions in Grand Junction, Colorado. Nth Degree Energy has been installing solar systems in the Grand Valley …

Alternative energy continues to fuel wide-ranging debate on a number of fronts. Mankind has known for decades that fossil fuels such as coal and oil are finite in their supply. There will reach a critical stage in which we find ourselves running out of these reserves. The question as to when this will happen is debatable but we are becoming …

One of the more popular uses of solar power in the home is the solar attic fan. As its name implies, a solar attic fan is powered and activated by solar power. It is installed into the roof of the attic, with its panels facing the sky. Why would one need a solar-powered attic fan? Well, for that matter, what …

Concentrated Solar Power, or “CSP,” and refers to the type of solar power which is created by concentrating sunlight into a small area, thus creating intense light and heat which can in turn create power and electricity. Concentrated Solar Power is one of the technologies which has been developed in order to harness the energy emitted by the sun and …

While some alternative energy solutions for the home, such as complete solar energy systems, require a major investment for their initial installation, there are others which are not so complicated. Solar lights are relatively simple to acquire and install, and are powered by clean energy. Since they usually require no wiring, they are very simple to set up. Solar garden …

With oil prices inching higher and higher, power costs tend to follow the same trend. Given that our daily life relies very much on the consumption of electricity, getting your power from alternate sources is an attractive option. The sun, water, and even wind are viable sources of power. What’s more, they are renewable sources of energy as they are …

I am working with a local roofer who installs cool roofs. It is truly amazing how much it can make a difference in the amount of energy your house uses to cool in the summer. We installed a cool roof and now see the interior of our house never getting hot in the summer as it used it before the …

A solar car is a vehicle, powered by electricity instead of fuel, which runs on solar energy obtained from the solar panels on its surface. The solar panels are often found on the roof of the vehicle. This type of vehicle is not entirely practical as of this moment, for obvious reasons. It needs to harness the power of the …

Fuel cells are electrochemical devices that combine hydrogen and oxygen in order to produce electricity. During the power generation cycle, water and heat are produced as a by-products. This is a far more ideal byproduct than the unclean emissions which are created by other methods of generating electricity. They will operate and generate power so long as fuel is supplied. …

A glacier, known as the Trotting Glacier, melts more water in a day than NY City uses in a year and has receded 9 miles in 5 years. The evidence is the ice core records that include CO2 and temperature levels reaching back 650,000 years. Each fume from a smoke stack and combustion engine output contributes to the seventy million …

Oil and its alternatives, such as biodiesel, are continuously in the news. When oil prices go up, it seems that everyone is affected. Many countries’ economies depend on oil. And this is one reason why people are looking for a cleaner and cheaper alternatives to our conventional fossil fuels. One of these alternative forms of energy is biodiesel. What is …

One form of alternative energy you can use in cooling your home is geothermal energy. This might sound surprising, but you can use the energy found in your own backyard by utilizing geothermal heat pumps. You can save up to 70% on cooling bills. The bad news is that professionally installed geothermal systems are too expensive. The good news is …

There are several solar pool heater kits available in the market these days. They cost between $3,000 to $4,000 for the materials and labor. In terms of recouping your initial investment, you could probably get your money’s worth in energy savings, within two to seven years. This all depends on the fuel costs in your area. Solar pool heaters are …
