East Bay Habitat for Humanity of Oakland, CA announced that it will add a 2.22 kW PV solar system to each of 26 low-income homes it will build in 2003, in Oakland and nearby Livermore, with technical assistance and financial help from Sky Power Systems of Castro Valley and other vendors.
SOLAR, WIND, AND FUEL CELLS TO FUEL ECONOMIC GROWTH, EXPANDING FROM $9.5 BILLION TODAY TO $89 BILLION BY 2012
Clean Edge, Inc., the Clean-Tech Market Authority, today released its annual "Clean Energy Trends 2003" report, projecting that solar photovoltaics (PV), wind power, and fuel cells will expand from a $9.5 billion market today to $89 billion by 2012. Additionally, Clean Edge released the top five clean-energy trends to watch in 2003 (available for free download at www.cleanedge.com).
DOI and DOE Announce Availability of New Report that Evaluates Renewable Energy Resources on Public Lands
As part of efforts to advance the President's National Energy Policy, the Department of the Interior's Bureau of Land Management and the Department of Energy's National Renewable Energy Laboratory today announced the availability of a new report that identifies and evaluates renewable energy resources on public lands.
The U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) today released its annual ranking of leading utility "green pricing" programs. Under green pricing, consumers can choose to help support additional electrical production from renewable resources such as solar and wind. More than 300 utilities in 32 states now offer these programs.
Wind-diesel system is the only power source on this isolated island in Estonia
23 Years After the Reagan Administration Removed Solar Panels, the White House Installs a New Solar Thermal and Electric System
The question is why are you interested in using solar or wind energy? Is it because you need some back-up electricity for when the utility grid is unavailable? Or is it because you want to spend less money per month on electricity?
As onlooking eyes filled with wonder watched, I assembled the three solar panels to the framework, it was time to hoist the finished array onto the roof. We were on the front side of the clinic and the ladder was not very good. We got the array to the top of the ladder but I could not get my helpers to go up on the roof.
News articles indicate that photovoltaics are already cost effective in Hawaii and some parts of California. Photovoltaics are also cheaper than electric grid power if you wish to power a remote home that is more than 2 miles from the nearest power line.
My view is that while we would all like to believe that the decision to use alternative energy sources by individuals will be justified economically ... or politically ... or culturally ... in fact the primary market growth for the products and services in this industry will be driven by responsible people who just want to feel good about the way they conserve or create energy.
Solar electric systems have high up front costs. Before going solar electric, you should conserve as much energy as possible so that your solar system can be smaller. Here are some tips on conserving electrical energy.
Steam, as with other forms of alternate energy has it's realm. Where steam excels above the other common systems, is in an application that requires large quantities of controllable, useable heat.
Maximum Power Point Tracking, frequently referred to as MPPT, is an electronic system that operates the Photovoltaic (PV) modules in a manner that allows the modules to produce all the power they are capable of.
The design is simple yet truly effective in offering to the building owner an aesthetically pleasing, lightweight photovoltaic roofing system that rests on flat or low slope roofs, requires no roof penetrations, protects roofs from weather and UV radiation and produces cost effective solar electric energy.
For emergencies there are all sorts of hand crank lights, solar flashlights, and low power LED flashlights. There's even a "shake-up" flashlight that uses a shaking motion of the hand to produce the needed power.
