Setting up a solar electric system is easy. The new source of power will integrate seamlessly with your existing utilities. Apart from settimg up the solar energy equipment, there will be no need to reconfigure or rewire your home. Our offerings include several pre-engineered, packaged systems for both residential and commercial applications, so there’s sure to be something that fits the needs of your home or business. Most solar panels last about 30 years, which means you will see the benefits of this new source of energy for decades to come.
Champion Energy is able to provide green power through the purchase of an environmental trading commodity known as a renewable energy credit (REC). RECs are created when a qualified renewable energy generation facility (like a wind farm or solar array) produces electricity. They represent the added value in terms of renewable energy’s environmental benefits and costs when compared to conventional means of producing power. We buy RECs from wind farms contributing electricity to your local grid, then ‘retire’ those RECs in direct proportion to the amount of energy you consume. In this way, you can be confident that every kWh you use is helping to promote and support the continued development of green energy infrastructure in your area.
By now you are probably thinking “why would these guys tell me the truth? They sell small wind turbines!”. Yup, guilty as charged. We also want happy customers, and the two are not reconcilable unless we are upfront with you, our customer. Truth is, wind turbine sales are a tiny part of our revenue, and while we would regret losing you, we will still be able to put food on our kids’ plates.
However, it has been found that high emissions are associated only with shallow reservoirs in warm (tropical) locales, and recent innovations in hydropower turbine technology are enabling efficient development of low-impact run-of-the-river hydroelectricity projects. Generally speaking, hydroelectric plants produce much lower life-cycle emissions than other types of generation. Hydroelectric power, which underwent extensive development during growth of electrification in the 19th and 20th centuries, is experiencing resurgence of development in the 21st century. The areas of greatest hydroelectric growth are the booming economies of Asia. China is the development leader; however, other Asian nations are installing hydropower at a rapid pace. This growth is driven by much increased energy costs—especially for imported energy—and widespread desires for more domestically produced, clean, renewable, and economical generation.
The first words of everyone calling us are “the wind is blowing here all the time”. People consistently overestimate how windy their place actually is. They forget about all the times the wind does not blow, and only remember the windy days. Such is human nature. Before even considering a small wind turbine you need to have a good idea of the annual average wind speed for your site. The gold standard is to install a data-logging anemometer (wind meter) at the same height and location as the proposed wind turbine, and let it run for 3 to 5 years. Truth is that it is usually much too expensive to do for small wind turbines, and while logging for 1 year could give you some idea and is the absolute minimum for worthwhile wind information, it is too short to be very reliable. For most of us, the more economical way to find out about the local average wind speed is by looking at a wind atlas, meteorological data, airport information and possibly the local vegetation (for windy spots the trees take on interesting shapes).
Modern turbines usually have a small onboard crane for hoisting maintenance tools and minor components. However, large heavy components like generator, gearbox, blades and so on are rarely replaced and a heavy lift external crane is needed in those cases. If the turbine has a difficult access road, a containerized crane can be lifted up by the internal crane to provide heavier lifting.
Biomass briquettes are increasingly being used in the developing world as an alternative to charcoal. The technique involves the conversion of almost any plant matter into compressed briquettes that typically have about 70% the calorific value of charcoal. There are relatively few examples of large-scale briquette production. One exception is in North Kivu, in eastern Democratic Republic of Congo, where forest clearance for charcoal production is considered to be the biggest threat to mountain gorilla habitat. The staff of Virunga National Park have successfully trained and equipped over 3500 people to produce biomass briquettes, thereby replacing charcoal produced illegally inside the national park, and creating significant employment for people living in extreme poverty in conflict-affected areas.

“Five New State Governors Aim for 100% Renewables” • Five governors-elect in Colorado, Illinois, Nevada, Connecticut, and Maine, states with a combined population of 26 million, put forth campaign goals of 100% renewable electricity. Currently, only California and Hawaii have a deadline to move to 100% zero-carbon electricity. [pv magazine International]

Between maintenance and repairs, it would greatly help and keep your cost down if you can do some of the work yourself: Being able to safely tilt the turbine tower up or down will save you money. Understanding how the turbine works, how to stop it safely, how to trouble-shoot at least the minor issues can keep you in the black. We understand that installing a wind turbine is not for everyone. In fact, towers are dangerous, and for a good installation the devil is in the details. An experienced installer can make a real difference in putting up a turbine that will work better, and be more reliable over time. We really encourage you to have a professional installer to do the initial installation. However, throwing up your hands and calling your installer for routine maintenance, or every time there is a minor issue, will likely make you an unhappy wind turbine owner (even if it is your installer’s dream).
The total number of commercial and industrial renewable energy deals will be even higher, as RMI's numbers refer only to contracts for large, off-site renewable energy projects. That means rooftop solar projects deployed by the likes of Ikea and Target are not included in the RMI deal tracker, which was updated this week at the Renewable Energy Buyers Alliance conference in Oakland, California.
Since the 1970s, Brazil has had an ethanol fuel program which has allowed the country to become the world's second largest producer of ethanol (after the United States) and the world's largest exporter. Brazil's ethanol fuel program uses modern equipment and cheap sugarcane as feedstock, and the residual cane-waste (bagasse) is used to produce heat and power. There are no longer light vehicles in Brazil running on pure gasoline. By the end of 2008 there were 35,000 filling stations throughout Brazil with at least one ethanol pump. Unfortunately, Operation Car Wash has seriously eroded public trust in oil companies and has implicated several high ranking Brazilian officials.
Meanwhile, we enjoy life grid intertied here in northern California. Our daughters and their families are nearby using their independent living skills to make their own homes. One daughter has designed and sold 300 off-grid or gridtie solar electric systems since the first of the year. The other is baking bread today and figuring out what to do with the multitude of tomatillos, squash and eggplant that are spilling out of our garden. I’m so proud of my tribe!
Nuclear power. After coal, the next largest source of our electricity is nuclear power. While nuclear plants don't cause air pollution, they do create radioactive waste, which must be stored for thousands of years. As accidents at Three Mile Island and Chernobyl proved, nuclear plants also carry the risk of catastrophic failure. And nuclear power can be very expensive.
A solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photovoltaic effect. The first solar cell was constructed by Charles Fritts in the 1880s. The German industrialist Ernst Werner von Siemens was among those who recognized the importance of this discovery. In 1931, the German engineer Bruno Lange developed a photo cell using silver selenide in place of copper oxide, although the prototype selenium cells converted less than 1% of incident light into electricity. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the silicon solar cell in 1954. These early solar cells cost 286 USD/watt and reached efficiencies of 4.5–6%.
