China’s omnivorous energy requirements have been attracting increasing attention as of late, as Beijing attempts to secure any and all sources of power for its growing industrial base.
Nowhere is this more noticeable than Beijing’s policies in the South China Sea, where Chinese (more…)

I have been reluctant to join the fray on what the recent Japanese disasters might mean to this or that issue. With active clients in Tokyo, these tragedies have had a personal effect, and my first thoughts have been for the personal well-being of these clients, their families, and their colleagues. So while the most important (more…)

Bing Energy, a company that manufactures components for polymer electrolyte membrane fuel cells (PEMFCs), which recently entered a partnership with Florida State University (FSU), has been subcontracted by the University of Central Florida (UCF) to develop a low-cost and high-efficiency 500 W portable PEMFC system.

The Washington Post has announced that in 2010, not a single new coal-fired power plant was constructed in the United States. This marks the second year in a row in which this has occurred. Coal remains the most abundantly used source of electricity, accounting for half of all power generation. However, a number of factors, such as the economy, lower natural gas prices, and (more…)

Ethiopia is not the first country to pops into minds when it comes to renewable energy. In fact, when thinking about renewable energy in Africa, Ethiopia still isn’t the first country that may come to mind. However, the country relies heavily on hydroelectric power as their primary means of generating electricity due to low fossil fuel reserves within the country. Despite not really (more…)

An old Israeli joke describes how God led Moses through the desert to the Holy Land for 40 years, through hardships and dangers, only to lead the Israelite nation to the only spot in the Middle East where there isn’t a drop of oil.
Two thousand years later, things have remained pretty much the same. Today, Israel is considered an “island-state”, with over 99% of its capacity produced from imported fossil fuels.
In alignment with global trends, Israel has experienced a recent surge of new ventures in the field, comprising commercial, academic and regulatory initiatives. Although a pioneer and home to world leaders in the RE field, the post-80s low oil pricing era left the Israeli RE industry relatively dormant in comparison with its blossoming high-tech activity.

The goal is to enable power generation from low-temperature geothermal resources at an economical cost. In addition to being a clean energy source without any greenhouse gas emissions, geothermal is also a steady and dependable source of power.
A new method for capturing significantly more heat from low-temperature geothermal resources holds promise for generating virtually pollution-free electrical energy. Scientists at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) are testing a new innovative approach to safely and economically extract and convert heat from vast untapped geothermal resources.

The earth is the water planet, so it should come as no great surprise that forms of water power have been one of the world’s most popular “renewable” energy sources. Yet the largest water power source of all – the ocean that covers three-quarters of earth – has yet to be tapped in any major way for power generation. There are three primary reasons for this:
The first is the nature of the ocean itself, a powerful resource that cannot be privately owned like land that typically serves as the foundation for site control for terrestrial power plants of all kinds;
The second is funding. Hydropower was heavily subsidized during the Great Depression, but little public investment has since been steered toward marine renewables with the exception of ocean thermal technologies, which were perceived to be a failure.
The third reason why the ocean has not yet been industrialized on behalf of energy production is that the technologies, materials and construction techniques did not exist until now to harness this renewable energy resource in any meaningful and cost effective way.

While coal-fueled power plants are directly responsible for roughly one-third of our CO2 emissions, the DOE indicates that coal is expected to dominate our domestic power generation at least for the next 25 years. Globally, the increased demand for coal-fueled electricity will translate into a 57% rise in related CO2 emissions by 2030 according to the IEA.
One technology that attempts to solve the CO2 emissions crisis is carbon capture and storage, or CCS. Generally speaking, CCS captures the CO2 emissions from coal power plants and other industrial sites and injects the CO2 into underground porous rock formations in hopes of permanent sequestration.
