5 Energy Predictions for 2011: Solar Soars As Fossil Fuel Costs Grow SET Energy
The year ahead appears poised to be another wild ride for the energy sector. A recovering US economy combined with continued strength in China and India will send oil and coal prices toward highs not seen since 2008. Meanwhile, solar and wind power will become increasingly attractive investments and grow their share of the energy pie.
Oil: Gasoline Gets Expensive Again
The financial collapse of September 2008 took the wind out of oil’s bullish run from $10 per barrel in the late 1990s to over $140 in mid-2008. But as the US economy regains its footing (even the housing sector by late 2011), gasoline is shooting back up toward $4 per gallon. Prices recently climbed back above $3 per gallon – meaning that Americans are again sending over $1 billion per day for overseas imports to serve our oil addiction. It’s time for our country to embrace the bicycle and more walking – but I’ll leave more on that for another post. I see gasoline increasing toward $3.25+ on $100 oil due to an inability of non-OPEC producers to increase supply that matches higher demand, particularly from China. And most OPEC nations seem reluctant to increase output levels while prices rise.
Solar Energy Environmental Mapper GIS Application
Solar Energy Environmental Mapper Web-Based GIS Application
Interactive web-based Draft PEIS map of proposed Solar Energy Development Draft PEIS alternatives and related information.
The Solar Energy Environmental Mapper is a web-based application to view map layers that were used to create the maps and conduct some analyses in the Draft PEIS. It displays the key layers used in the PEIS with the ability to zoom and pan to areas of interest, and display and query data. The application requires a web browser with Adobe Flash Player 10 (or higher) installed and is compatible with leading, current, web browsers.

Residential Solar Heating Collectors – Renewable Energy
Solar collectors are the heart of most solar energy systems. The collector absorbs the sun’s light energy and changes it into heat energy. Solar collectors heat a fluid, either air or liquid. This fluid then is used to heatdirectly or indirectlythe following.
- Water for household use
- Indoor spaces
- Water for swimming pools
- Water or air for commercial use
- Air to regenerate desiccant (drying) material in a desiccant cooling system.
There are several types of solar collectors used for residences. These are flat-plate, evacuated-tube, and concentrating collectors.
Flat-Plate Collectors Flat-plate collectors are the most common collector for residential water-heating and space-heating installations. A typical flat-plate collector is an insulated metal box with a glass or plastic covercalled the glazingand a dark-colored absorber plate. The glazing can be transparent or translucent. Translucent (transmitting light only), low-iron glass is a common glazing material for flat-plate collectors because low-iron glass transmits a high percentage of the total available solar energy. The glazing allows the light to strike the absorber plate but reduces the amount of heat that can escape. The sides and bottom of the collector are usually insulated, further minimizing heat loss.
Solar Panels More Affordable With New Technology?
MIT researchers are looking into new solar panel technology
Over the past 3 years, the price of solar panels has dropped dramatically – in some cases by 2/3 of the original cost. Yet, with use of new technology, could solar panels be even more affordable?

Do solar energy panels for your home make sense?
I have heard solar PV panels cost $ 75,000.00 to save about $ 2,200.00 per year and only last 20 to 24 years and need replacement. To finance that cost $ 123,000.00 over 24 years at 4.6 intrest.This sounds like a financial disaster. Any thoughts…
If I spend 75k on panels I will save a lot more than $ 2,200.00 per year? The cheap quotes out there dont seem to exist around the mid west. There is much info rate life span at 24 yrs. and losing effectiveness as they age.
As single home solution might not be cost efficient when you try to use the energy “1:1″ in your home.

NREL solar researcher honored with World PV Award Dr. Lawrence Kazmerski, a leading research director at the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL), received the World PV Award at the Fourth World Conference on Photovoltaic Energy Conversion on May 9 for his outstanding contributions to the worldwide advancements of photovoltaic (PV) science and technology.
The award, sponsored by professional organizations from the European, Asian-Pacific Rim and American photovoltaic communities, recognizes superior and sustained leadership in solar photovoltaics.
Solar Photovoltaic Cells: How They Work
HOW SOLAR CELLS ARE MADE
The photovoltaic cells contain one or more p-n junctions. The “p” material is normally connected to a metal base that becomes a positive terminal. The topside of the wafer with “n” material usually has a grid of electrical contacts, which do not cover the entire face of the cell since they are not transparent to light. The contacts connected to n-regions are paralleled and routed to a negative terminal. Sunpower Corp. has recently developed a technology in which electrical contacts are on the back of the cell, which leaves the entire front surface available for sunlight yielding higher efficiency. To reduce the percentage of the photons that are reflected off the semiconductor material and increase the number of photons that will become absorbed, an anti-reflective coating is usually put on the semiconductor.

Replacing Batteries with Energy Harvesting Methods
The most probable development that would put an end to our battery addiction is energy harvesting. Sometimes called also energy scavenging, it means using energy which is “freely” available in the environment to power up the devices that would traditionally rely on batteries to function. As we will see, this notion has been around for much longer than conventional electric batteries.
Energy harvesting has been around us for centuries. Before electricity was invented people used the windmills and watermills to ease up their work, or even the solar energy to heat water in metallic cisterns. Besides being eco-friendly, these methods would have provided free energy and virtually inexhaustible source.
Closer to our times (and somewhat closer to the modern notion of energy harvesting), the automatic watches and then wristwatches started to use ambient energy (mechanical energy in this case) to put into motion a self-winding mechanism. Contrary to the general opinion (I personally was surprised to find about it about 6-7 years ago) the technology exists since the early 1770s, when Swiss watchmaker Abraham-Louis Perrelet invented a mechanism that automatically winded a pocket watch. The mechanism used the mechanical energy generated by the movement of the human body and used it to wind the spring inside the watch. The technique stagnated until the 1920s when it was enhanced and applied to the wrist-watches that would have started to become popular at the time. Now-a-days, the automatic wristwatch is an ordinary existence in our lives and one of the most common examples of energy harvesting in action.
