Coal Deathes and Pollution

2009-10-28T17:08:00.005+02:00

A new report by the US National Academies of Science, Engineering and Medicine estimates the damage to public health and environment from power plants and vehicular emissions. The report's findings are unbelievably high.

The cost of power plant emissions in 2005 was $62 billion dollars while that of the automotive sector (light, medium and heavy vehicles) is $56 billion. However, the report didn't take into consideration the effect of greenhouse gas emissions and global warming. Adding these factors would further increase the financial impact of these emissions.

The implications of this is that the damage of coal emissions costs around 3.2 cents per kilowatt hours. Electricity produced from coal costs between 5 to 6 cents per kilowatt hours. If the damage of coal was added, the total cost of coal would be around 8 cents per kilowatt hours. At this level, unsubsidized nuclear, gas and even wind would become competitive with coal power plants.

The report examined 406 coal power plants. The surprising this is that only 10 percents of these coal plants account for 43 percent of the coal's impact on public health. So if the US shuts down its dirtiest plants, 9000 lives would be saved and a 20 percent cut in greenhouse emissions would be achieved.

Renewable Energy and Energy Efficiency Could Create 4.5 Million Jobs

2009-10-26T19:12:00.002+02:00

According to a new report by American Solar Energy Society (ASES) and Management Information Services Inc. (MISI), 4.5 million jobs could be created by 2030 if the US government seriously tackles climate change.

The report is titled Estimating the Jobs Impact of Tackling Climate Change. In this report, the net jobs created if the US commits to reducing CO2 emissions by 1.2 billion by the year 2030 is estimated. These net jobs created after taking into consideration the jobs lost during this period.

Last January, ASES has released a report titled, Tackling Climate Change in the U.S. The society found that the US could keep emission levels constant through 2030 by implementing energy efficiency measures. In addition, deep CO2 emissions cuts could be achieved if renewable energy technologies was applied.

The new report found that renewable energy and energy efficiency deployment would have a neutral or better net cost. This results from the fact that energy efficiency would end up saving the country more money than the costs required to deploy renewable energy technologies.

Air CSP Tower in Germany

2009-03-26T18:55:00.009+02:00

Concentrating solar power (CSP) is considered to have the best potential to supply solar power on utility scale basis. CSP plants had been build as early as the 1970s, but new technological developments are causing CSP to be considered as an effective solution to generate renewable power.

Kraftanlagen Munchen, a construction company, finished constructing a new 1.5 MW (Mega Watt) experimental solar thermal plant in December 2008. This new plant is unique because it's the world's first solar thermal plant that uses air, instead of oil or molten salf, as the medium for heat transport.

Previously, molten salt and oil were used because of their high specific heat capacity. This helps in having low volume flow rates and low pumping losses while the liquid is being circulated to heat up.

The downfall of using liquid medium is that the concetrated solar radiation (500 to 1000 suns) is in the air and that to heat the liquid the heat must pass through a wall. This causes loses in the heat exchange process thus lowering the efficieny of this method.

The new method used by the Jülich power tower takes advantage of the volumetric effect. Ambient air is sucked through a blackened porous structure on which the solar radiation is focused. This causes the air's temperature to rise, the hot air is fed to a heat recovery steam cycle (used for the exhaust heat of gas turbines in combined cycle plants). The heat recovery steam cycle generate steam which drives the steam turbine and generate electricity.

At night exhaust gases from gas turbines can be used to feed hot air to the heat recovery steam cycle and keep the system operation 24 hours per day. Also, heat storage could be used to drive the plant at night.

"The Jülich plant features a storage system consisting of honeycomb-type ceramic blocks, through which air passes in one direction for charging, and in the other for discharging. As the discharged air has the same temperature as when charging, no energy is lost, making the system highly efficient."

Solyndra Receives a US $535M DOE Loan

2009-03-25T11:31:00.003+02:00

The U.S. Department of Energy (DOE), under the Energy Policy Act of 2005, has given it first loan guarantee to Solyndra Inc. This loan will be used by the company, known for its cylindrical solar photovoltaic (PV) systems, to expand its solar panel manufacturing capacity in California.

Dr. Chris Gronet Solyndra's CEO and founder said that the loan will help Solyndra to achieve the economies of scale needed to deliver solar electricity at prices that are competitive with utility rates. This will in turn help create new jobs and at the same time mitigate global warming.

Solyndra will use the loan to start construction of its new fabricating plant (Fab 2). Once competed the plant will deliver PV panels having a total generating capacity of 500 megawatts each year.

Fab 2 is expected to produce solar panels sufficient to generate up to 15 gigawatts of renewable energy over its life span. This will help avoid the emission of 300 million metric tons of carbon dioxide.

The company said that the construction of this complex will employ approximately 3,000 people and that the operation of the facility will create over 1,000 jobs. Solyndra and DOE will finalize the transaction by completing paperwork and making sure that the company meets all requirements for the loan.

Solar Installed Capacity Up 17% in 2008-Report

2009-03-24T20:47:00.005+02:00

An annual report released by the Solar Energy Industries Association (SEIA) shows that in 2008 the total U.S. installed solar power increased 17% to 8,775 megawatts (MW).
The report indicates that the solar industry has achieved a record growth for the third year in a row. In 2008, 1,265 MW of solar power was installed.

This includes 342 MW of solar photovoltaic (PV), 139 MWTh (thermal equivalent) of solar water heating, 762 MWTh of pool heating and an estimated 21 MW of solar space heating and cooling.

The report also states that no new concestrating solar power (CSP) plants had been built in 2008. But plans to build 6 gigawatts (GW) of CSP plants are in the pipline. California’s Mojave Desert, Arizona and Florida are some places where these plants are supposed to be constructed.

States that led in grid-tied PV installation were California (178.6 MW), New Jersey (22.5 MW), Colorado (21.6 MW), Nevada (13.9) and Hawaii (11.3 MW).

For solar water heating systems, Hawaii led states, installing 37% of the total U.S. systems in 2008, followed by Florida (20%), California (7%), Colorado (5%) and Arizona (5%).

A total of 42 states and the District of Columbia now have net metering rules allowing owners of solar energy systems to sell excess electricity back to the grid. However, these rules differ from state to state and a unified national policy is necessary, SEIA said.

The U.S. solar industry in 2008 increased domestic PV manufacturing capacity by 65% to 685 MW of capacity.

Solyndra: New Cylindrical Solar Panels

2008-11-01T09:56:00.004+02:00

Solyndra, a 3 year old company, is producing unconventional solar panels. Instead of the old flat panels, Solyndra came up with new cylindrical panels. These panels collect sunlight more efficiently across a broader range of angles and catch light reflected off the roof itself.

To build these solar panels, Solyndra uses thin film solar cells. Thin film solar cells aren't as efficient as silicon cells but they cost less to manufacture. Very small amount of CIGS, copper indium gallium diselenide, is deposited in ultra thin layers along the surface of glass or metal. VP of business development Kelly Truman said that their process uses just a bit more than a micron of copper indium gallium diselenide, or CIGS.

On the roofs of Solyndra's office buildings, the first modules have been installed.
The solar tubes look like reverse fluorescent light bulbs. These tubes are not bolted to the roof because they are less susceptible to wind damage than traditional flat solar panels.

First Solar Panels for your Home

2008-10-30T18:18:00.003+02:00

First Solar Inc. announced on Wednesday that it will start supplying solar panels for households. Up to this point First Solar supplied panels for huge solar power plants in Europe and Asia. First Solar currently have plants in Germany, Ohio and Malaysia. First Solar will sell SolarCity Corp., a residential-installation company, enough panels for 25,000 homes in the next five years.

SolarCity sells residential solar power systems through a 15-year "no money down" lease program. However, if a home-owner chooses to pay a $1,000 down payment, the lease payment and utility bill will cost him less than his/her old utility bill.

The high first payment to install a solar system has been the biggest obstacle facing residential solar power. But with First Solar's low cost panels, prices will go down.

First Solar's panels are cheaper to produce than traditional solar panels. However, the panels are less efficient thus requiring more roof space compared with more expensive silicon panels.

CSU Going Solar

2008-10-27T18:04:00.003+02:00

The state of California and SunEdison announced an agreement to provide affordable solar power at 15 California State University (CSU) campuses and the CSU executive office. Through this partnership, an eight megawatt (MW) solar photovoltaic power system will be installed at CSU campuses giving zero-emissions electric power.

During the first year of operation, the eight MW system is expected to deliver approximately 12 million kilowatt hours of clean renewable energy. This amount of solar generated electricity represents five percent of the entire CSU system’s yearly energy consumption.

Over the life of the contract, the partnership will offset approximately 9,485 metric tons of carbon dioxide, which is the equivalent of removing 48,937 cars from the road.

New SunEdison solar panels will be installed on rooftops, atop parking canopies and in ground-mounted arrays at various locations in the CSU campus.

As state government’s contract manager, the Department of General Services (DGS) negotiated the alternative financing method known as a power-purchase agreement for CSU. The agreement allows CSU to buy renewable power at or below current retail rates while avoiding the cost of installing the system. Under this agreement, SunEdison will finance, build and operate the solar panels for 20 years.

The State of California-SunEdison solar purchase agreement arranged by DGS should yield a total of approximately 20 MW of new renewable energy for the state.

It consists of installing the following systems:
1- 7 MW of solar power at five state prison sites and three state mental hospitals. 2- Since 2006, 4.2 MW of solar power have already been deployed at eight other state facilities through similar power purchase agreements.

DGS also recently launched an online database identifying where solar panels, fuel cells, wind turbines and other green energy technologies are generating renewable power at state office buildings, prisons, hospitals and college campuses which can be found at www.RenewableEnergy.dgs.ca.gov.

California’s push to fight global warming and increase renewable energy will also boost our economy. According to an economic study released yesterday by the University of California at Berkeley and Next 10, California’s policies will create as many as 403,000 jobs in the next 12 years and household incomes will increase by $48 billion.
