Brazil, the third largest territory in the Americas and the fifth largest in the world, with nearly 200 million people, has suffered with the environmental problems generated by the traditional model of dumping their waste in landfills. That process unfortunately, turns worse by the inhabitants practices of simply throwing the waste away on areas without any control or care, constituting the so-called "lixões" (slang meaning "big garbage" in Portuguese language).

With Presidential direction and Congressional support, NASA's wellspring of talent could help foster the creation of solar power satellites - spacecraft that circle the Earth and beam the energy they generate down to the ground for distribution as electricity.
Not all the alternative generation of energy is really taken into account because numerous small-scale projects are inevitably overlooked. The Energy Information Administration (EIA) does make available figures on the economy, crude oil prices, and alternative resources to the best of their data collecting ability. This information is almost constantly revised as more data is available but the changes and revisions are not especially dramatic. The change in energy consumption and sources of energy is an evolutionary process and not a revolutionary process.
This article deals with the present energy mix and tries to discover how the future energy mix should look in order to be sustainable and significantly reduce environmental impact, for example reduced CO2 emissions. It should be less dependent on the fossil fuels, have increased reliability, have fuel cost with reduced price fluctuations and be able to successfully meet the future demand for energy that just gets larger and larger as world energy requirements increase with the new lifestyle choices.
In December 2008, the 84-acre coal ash surface impoundment at the Tennessee Valley Authority's (TVA) Kingston coal-fired power plant failed and released over a billion gallons of coal combustion waste. It's estimated that this release could ultimately cost a billion dollars to remediate because 300+ acres were covered by the flood of coal ash slurry. At question is does the U.S. need more traditional coal-fired power plants and what to do with the ash slurry mess?
The Dow Jones Industrial Average recorded its best month in nearly seven years, posting an 882-point boost since Friday, July 3. In fact it was the best July for Wall Street in twenty years. Gains for the week for the Dow and NASDAQ were meager however, with both gaining less than a percent. The 20SSI decreased 5.8% from last week's close but the net gain since July 3 was nearly 22 points.
One university's quest to revolutionize the built environment.
The U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) today released its annual assessment of leading utility green power programs. Under these voluntary programs, consumers can choose to help support additional electricity production from renewable resources such as wind and solar.
This week was the biggie with DJIA up 6.83%; NASDAQ +6.03% and this index rocketing 41.54%.
The global financial crisis dominated the news media in the second half of 2008. The crisis is certainly negatively affecting the sustainable energy market in the short term. On the other hand, the crisis has generated broad public demand for government investments that create employment and stimulate the economy.
There has been a lot of progress made recently in improving energy efficiency, but it's important to look at the process and your house as a whole - an improvement in just one area of your home will not necessarily work.
The aviation industry produces only about one-ninth as much carbon dioxide as motor vehicles do. However, environmentalists are vocal about emissions from aviation, because they tend to go into the upper atmosphere, where some scientists say the impact is greater.
The U.S. housing crisis is the main cause of the global financial crisis. Therefore, the availability of loans for green field installations seems to be limited. However, financing for residential and commercial PV applications is still available.
The oil and gas industry were provided a $17 billion tax credit from 2007-2011 in the latest energy bill passed last December. That's $3.4 billion in tax credits for each of five years.

The addition of energy storage to an existing or new utility-scale PV installation allows system owners and operators the opportunity to capture additional revenues. Traditional storage plus solar applications have involved the coupling of independent storage and PV inverters at an AC bus or the use of multi-input hybrid inverters. An alternative approach - coupling energy storage to PV arrays with a DC-to-DC converter - can help maximize production and profits for existing and new utility-scale installations. DC-Coupled Utility-Scale Solar Plus Storage leads to higher round-trip efficiencies and lower cost of integration with existing PV arrays and at the same time, opens up new revenue streams not possible with traditional AC-coupled storage, including clipping recapture and low voltage harvesting, while being eligible for valuable tax incentives.
