Micro Generation is defined as the generation of electricity or heat energy on a small scale, typically for use on a domestic scale and generated by methods that do not contribute to the depletion or damage of natural resources, such as through the use of solar panels.[read more]

New Kind of "Tandem" Solar Cell Developed

March 28, 2015 by Energy @ MIT

Solar Cell Invention

Researchers have developed a new kind of solar cell that combines two different layers of sunlight-absorbing material in order to harvest a broader range of the sun’s energy. The development could lead to photovoltaic cells that are more efficient than those currently used in solar-power installations.[read more]

The solar industry recently attracted attention from two Silicon Valley tech giants: Apple and Google. Their investments in solar technology simultaneously underscore the growing interest in solar from the business world, and highlight one of the industry’s key challenges: long-term financing.[read more]

The Secret to Cost Effective Energy Storage

March 27, 2015 by Nigel Morris

I am as optimistic as anyone about energy storage and try as I may I can’t (in my own head) separate the growth in electric vehicle sales and the inevitable flood of lower cost energy storage for stationary applications. There are deep and close connections that will flow both ways.[read more]

China Energy Needs and Sources

If you follow energy discussions, you will often hear one of two visions of China’s energy system emphatically described by various pundits and advocates. At first blush, the two visions seem fundamentally in conflict. Only one must be true! How can China be both “green” and “black” at the same time?[read more]

The Challenge of Unlocking Solar Capacity in the Pacific Islands

March 21, 2015 by Katherine Tweed

Pacific Island and Solar

It’s no secret that most islands pay a high price for electricity. From Bermuda to Fiji, the cost of electricity would shock even Europeans. But for most island economies, it’s not as simple as just swapping imported fossil fuels for renewable generation, even if the high-level economics seem promising.[read more]

The Real Prize: India Energy Planning

March 19, 2015 by Tobias Engelmeier

India's solar efforts have not been terribly impressive, partially because of the expectations the government has put on itself with a 100 GW target. In fact, growth in the sector is picking up significantly. But that growth isn't driven by sustainable policies, but by one-off measures, and that it is not enough.[read more]
