An Assessment of the Environmental Impacts of Concentrator Photovoltaics and Modeling of Concentrator Photovoltaic Deployment Using the SWITCH Model
Here’s the new view in the latest IPCC Special Report on Renewable Energy Sources:
In 2008, global geothermal energy use represented only about 0.1 percent of the global primary energy supply. However, by 2050, geothermal could meet roughly 3 percent of the global electricity demand and 5 percent of the global demand for heating and cooling.
That dramatic expansion of scope – a factor of 15 on a global scale – is a function of new technology options and forecasts for higher fossil fuel prices. But it is only one example.
Another technology undergoing a dramatic expansion of options is that of hydropower. Conventional dams, large and small, use either a natural, or more commonly, an artificial “head” or drop to harness energy.

Berkeley Rural Energy Group's Seminar:
Speaker: Jacob Winiecki from SIMPA Networks will be presenting on their design and implementation their novel technology, solar systems that use pre-paid energy meters that use cell networks to electronically transfer payments.

At the African Energy Ministerial Meeting in Johannesburg, South Africa, today, both high-level planning and on-the-ground energy projects were visible, and truly inspiring. In a five hour Green Household Energy Solutions Expo that I had the true pleasure to chair, the Minister of Economic Development for South Africa, Mr. Ebrahim Patel, kicked off the discussion by saying that South Africa was committed to growing nation’s clean energy generation capacity for both domestic use and for export and in the process create green jobs.
The meeting marks a key chance for integration and coordination as the last regional ministerial meeting before the COP17 Climate Conference in Durban, South Africa in December of this year. The room was packed, with over 15 ministers in attendance, and the discussion turned to the benefits of regional integration of transmission systems, building wind, geothermal, and large-scale solar energy projects.
However, the focus and the stars of the meeting were the innovators at the household and local community level who showed the possibilities that exist with a range of new approaches – some technological but many managerial and social as well.
