Engineers are developing a solar panel composed of nano-antennas instead of silicon semiconductors. They say that through the use of these antennas, a much higher conversion rate from light into usable energy can be achieved — and could lead to a more cost-effective way to harvest and utilize “green” energy. ScienceDaily: Solar Energy News
Some laboratories have achieved impressive efficiencies under concentrated sunlight. SunPower Corp. is much closer to the market. The California-based company recently produced a record-setting 24.2 percent efficiency large area silicon wafer in its Philippine factory. Heat loss from available silicon solar cells reduces the maximum efficiency to around 30 percent. Professor Xiaoyang Zhu at the [...]
Renewable Energy and Data Centers
As organizations like Greenpeace pressure Internet companies to use more energy from renewable sources, data center operators are struggling with the best approach to renewable power. To get some perspective on the issue, we spoke with John Stanley, a researcher at The 451 Group who specializes in “Eco-Efficient IT” and the intersection between data centers [...]
Switching on India’s solar future
India is confronted with the triple challenges of climate change, energy security and economic development with political will and technological prowess. But will that be enough to bring in the capital it needs to ensure a transition to green growth? India already has a head start in the race for renewables, ranking fifth in the [...]
Melaka invested RM3.2 million in a solar energy plant.
KUALA LUMPUR: Melaka will be declared a “developed state” come Oct 20 by Prime Minister Datuk Seri Najib Tun Razak. The declaration will be done via “online” from Kuala Lumpur, said Melaka Chief Minister, Datuk Seri Ali Rustam. The quest to get developed status for the state under a 10-year plan known as Melaka Maju [...]
