California has some hurdles to overcome in meeting the most ambitious clean energy goal in the country. Governor Jerry Brown signed SB 100 today, requiring that 100 percent of the state’s electricity must come from solar, wind and other emissions-free sources by 2045. For the fifth largest economy in the world, that would mean a […]

An omnidirectional wind turbine that works in the middle of big cities, which could “take urban energy harvesting to another level”, is the UK’s James Dyson Award winner for 2018. Designed by Lancaster University students Nicolas Orellana and Yaseen Noorani, the O-Wind Turbine is made for high-density urban environments, instead of the open fields where […]

UC Berkeley engineers have created a device that dramatically reduces the energy needed to power magnetic field detectors, which could revolutionize how we measure the magnetic fields that flow through our electronics, our planet, and even our bodies. “The best magnetic sensors out there today are bulky, only operate at extreme temperatures, and can cost […]

Fusion, the power that drives the sun and stars, produces massive amounts of energy. Scientists here on Earth seek to replicate this process, which merges light elements in the form of hot, charged plasma composed of free electrons and atomic nuclei, to create a virtually inexhaustible supply of power to generate electricity in what may […]

The Abu Dhabi Fund for Development (ADFD) has announced that it will fund the development of a 30MW waste-to-energy facility in Sharjah. The national entity has approved a $33 million concessionary loan for the project, which follows on from its initial commitment to the project earlier in the year. The project is said to be […]

As we enter a more environmentally-conscious age, we need to inevitably build more ecologically responsible and sustainable cities. Creating buildings with the lowest possible energy consumption and carbon emission production, while still being aesthetically pleasing, is a challenge bringing together great minds to change the way we think about our living and working spaces. Here […]

If you’ve ever waited in a buffet line or been served in a high school cafeteria, you’ve seen them. Rows of metal pans immersed in a bath of hot water. According to food service industry veterans, restaurants, hotels and school cafeterias typically use inefficient natural gas or electric resistance steam-based systems to heat those pans […]

The residential solar market has slowed in key U.S. markets. There’s no shortage of reasons for the stagnation. Fewer early adopters, the impact of Section 201 tariffs, changing state policies and persistently high customer-acquisition costs are all contributing to the decline in the number of U.S. households choosing to go solar. The tepid performance of […]

Ocean waves contain lots of energy that could be harvested, especially if methods for energy extraction could be improved. Now researchers have demonstrated a new type of structure that concentrates the energy of passing waves into a smaller area, thereby making energy harvesting easier. With further development, the technique could soon find practical deployment in […]

Tucson Electric Power Co. hasn’t actively campaigned against a ballot proposition that would require state-regulated utilities to dramatically increase their use of renewable energy sources like solar and wind. Until now. UNS Energy Inc., parent of TEP and sister rural utility UNS Electric, has formed and plans to fund two political action committees to oppose […]
