Solar Energy Breakthrough Could Cut Costs By More Than 50%

A US-based company has successfully tested a revolutionary solar panel that is expected to cut the costs of photovoltaic solar power generation by more than 50 per cent, and herald a new era of improved efficiency and lower production costs of solar energy globally.

The panel, known as the Alubond Solar Collector Panel (SCP), was created by American Building Technologies, a subsidiary of the UAE-based multinational group Mulk Holdings. Commenting on the breakthrough, a spokesman for Mulk said, “We hope the success of this project will lead to an upsurge in the development of more solar energy plants, which will not only lessen the strain on existing energy resources, but also severely reduce the pollution levels that are currently witnessed in power generation.”

NASA Says Cut in Soot Emissions Would Slash Global Warming

Nasa scientists have told government’s that a simple cut in worldwide emissions of soot could lead to a dramatic reduction in the effects of global warming, as well as preventing hundreds of thousands of deaths from air pollution.

Soot contains black carbon, thought to be the second largest cause of global warming after carbon dioxide. Whilst airborne, it it spread around the globe by wind, heating the atmosphere by absorbing and releasing warmth from the sun’s rays. When it falls to the surface it also darkens snow and ice in polar regions or high mountain ranges, further reducing the Earth’s ability to reflect solar radiation.

Cutting soot emissions has a virtually instantaneous effect since it disappears rapidly from the earth’s atmosphere, unlike CO2, which can linger for hundreds of years.

Zimbabwe: A Cry for the Environment

Zimbabwe, which currently faces seemingly intractable social, political and economic problems, has some of the worst environmental indicators in the world with ecosystems either in decline or under severe threat.

Suffice to state, the country did institute some good environmental protection programmes in the decade following the attainment of independence from British rule in 1980, markedly, Zimbabwe has about half of the world’s population of black rhinoceroses, an endangered species. During that period, the government even went as far as adopting a radical policy of shooting poachers on sight in order to protect endangered animal species.

In recent years, however, Zimbabwe has experienced desertification, soil and water pollution, slash and burn agriculture resulting in soil erosion mainly caused by an unplanned land resettlement programme initated by incumbent President Robert Mugabe’s government in 2000.

Yale University’s 2008 environmental performance index (EPI) which ranks 149 countries according to a weighting of carbon and sulfur emissions, water purity and conservation practices, positions Zimbabwe at number 95 thus highlighting the grim state of the environment in the country.
