Solar Panels Banned in Chinese Neighborhood
In China it’s not unusual to see private residents to make the move to solar power. Like in any country the initial expense is high, but putting a few solar panels on your roof will pay off in the long run. It’s good for you and it’s good for the environment. Everybody wins, right?
Solar panels strictly forbidden

A worker adjusts the solar panels on the roof of the Max-Schmeling-Halle in Berlin in 2009. The German government wants to slash its support to the solar energy industry to prevent the market from overheating, a member of Chancellor Angela Merkel’s CDU party said Tuesday.

The unit comes in two distinct part: 1. Monopole Tower 2. Inverter and Control Box
Monopole Tower
The towers come in different heights – starting at 6m for 1kw and up to 12 and 16m for the 5kw. The towers are set in a concrete foundation and the ground needs to be suitable to dig down to up to 3m in depth. A concrete base is generally not required for the 1kw and 2kw turbines but is a requirement for the larger turbines.

Challenge
Wind energy is one of the world’s fastest growing energy sources. The growth has also highlighted major technical issues facing the Canadian wind sector, ones that are due in large part to the Canadian context of a huge landmass with diverse terrain and a Nordic climate. The technical challenges affect all aspects of the entire value chain from resource assessment and wind power extraction to wind power integration and optimization. These technical issues limit the ability of the Canadian wind industry to compete in the growing wind energy market and achieve its full potential.
Highly efficient solar cells could result from quantum dot research
ScienceDaily (June 18, 2010) — Conventional solar cell efficiency could be increased from the current limit of 30 percent to more than 60 percent, suggests new research on semiconductor nanocrystals, or quantum dots, led by chemist Xiaoyang Zhu at The University of Texas at Austin.
Zhu and his colleagues report their results in this week’s Science.
The scientists have discovered a method to capture the higher energy sunlight that is lost as heat in conventional solar cells.
Renewable Energy TV: Harbor Freight 45 Watt Solar Panel Kit
Found a lot of people having problems with adding additional length to the leads from the panels to the controller since they are only 10-12 feet long. here is some great info I found from Marshall at All Experts…..
Question Hi Marshall – I recently bought a 45 watt solar panel system (harbor freight) that is actually working fairly well. My problem is that the wire leads from the panel to the regulator are only 11’ long. There’s 3 leads (2 wires from each panel + & -) and they appear to be about 18 – 22 ga. Can I extend these leads to maybe 24’ & what type & ga wire should I use for the extension. I plan to leave the original leads & use a terminal block and then run one wire each (+ & -) to the regulator. Thanks greatly for any help, ideas, & advice…..Mark
Answer Hello Mark,
Global Warming: Scientists’ Best Predictions May Be Wrong
ScienceDaily (July 15, 2009) — No one knows exactly how much Earth’s climate will warm due to carbon emissions, but a new study suggests scientists’ best predictions about global warming might be incorrect.
The study, which appears in Nature Geoscience, found that climate models explain only about half of the heating that occurred during a well-documented period of rapid global warming in Earth’s ancient past. The study, which was published online July 13, contains an analysis of published records from a period of rapid climatic warming about 55 million years ago known as the Palaeocene-Eocene thermal maximum, or PETM.
“In a nutshell, theoretical models cannot explain what we observe in the geological record,” said oceanographer Gerald Dickens, a co-author of the study and professor of Earth science at Rice University. “There appears to be something fundamentally wrong with the way temperature and carbon are linked in climate models.”
Biofuel Production
A Biodesign Institute at Arizona State University research team has developed a process that removes a key obstacle to producing low-cost, renewable biofuels from bacteria.
The team has reprogrammed photosynthetic microbes to secrete high-energy fats, making byproduct recovery and conversion to biofuels easier and potentially more commercially viable.
“The real costs involved in any biofuel production are harvesting the goodies and turning them into fuel,” said Roy Curtiss, of the Institute’s Center for Infectious Diseases and Vaccinology and professor in the School of Life Sciences. “This whole system that we have developed is a means to a green recovery of materials not requiring energy dependent physical or chemical processes.”

Moving to create clean energy jobs, fight climate change and set America on a path to energy independence, Reps. Edward J. Markey (D-Mass.) and Todd Platts (R-Pa.) on Wednesday introduced the American Renewable Energy Act, which would require America to generate one-quarter of its energy from “clean energy sources” by 2025.

Have you ever wondered if what you know about the causes of land pollution is accurate? Consider the following paragraphs and compare what you know to the latest info on the facts about solar energy.
Solar energy is not only the cleanest energy you can find, it also takes an important part in almost all natural process in our planet. So why can’t we manipulate the energy and use it properly for our daily need to substitute the nearly extinct natural energies? Solar energy is making a big impact today. In the world we live, we have put major strain on natural resources. Solar energy facts for kids in New Zealand are considered unnecessary by some. When winter hovers over New Zealand, it may seem that day after day is cloudy and grey – especially in some parts of New Zealand.
Solar energy’s potential is off the charts. The sun’s energy, known as solar radiation, can be converted into various forms of power, such as electricity and solar-thermal (or heat). Solar energy technology is fairly new, and it has some downsides that have not been resolved yet. The cost of producing electricity via solar energy is 12 cents per kWh using solar thermal and 23 cents per kWh using PV cells, according to Gilbert Metcalf.
