The United States has the lowest renewable energy penetration among the top 5 global economies, Moody s Investors Service concluded in an infrastructure and project finance report released Monday. Leading that list is the European Union and U.K., followed by China, India and Japan.
The analysis blames the laggard status on weak U.S. federal policies, including the lack of a national renewables mandate and inconsistent tax incentives for wind and solar. Where renewables have thrived in the United States, Moody s said, is in large part due to their growing cost competitiveness and local policy.
Analysts and advocates agree U.S. federal policy has not sufficiently championed renewables growth, but see reasons for optimism with President Joe Biden indicating his support for clean energy. It is really important for the federal government to lay down some markers and set some goals, said Uday Varadarajan, a principal in Rocky Mountain Institute s (RMI) carbon-free elect

Puget Sound Energy s new long-term resource plan is failing to live up to the promise of Washington state s ambitious clean energy legislation by leaving the door open for more carbon dioxide-emitting resources, according to environmental advocates and Washington residents.
The debate over PSE s draft integrated resource plan (IRP), seen at a Feb. 26 meeting held by Washington regulators, is the latest example of a conflict over the degree to which natural gas will be needed to back up renewable energy, and whether or not using alternative forms of natural gas like biogas alleviates emissions concerns.
The IRP serves as a launching pad for how PSE, the state s largest utility, will implement Washington s 2019 Clean Energy Transformation Act (CETA), which requires utilities to transition toward carbon neutrality by 2030 and 100% clean energy by 2045. PSE and other Washington utilities must file their first CETA implementation plans by Oct. 1, and the plan must be consis
Perovskite solar cell with cesium-titanium dioxide nanotubes
A global research group has developed a perovskite PV cell with titanium dioxide nanotubes doped with cesium. It purportedly offers better short-circuit current and power conversion efficiency than cells without cesium nanoparticles. They say it has optimal thermal stability under temperatures up to 800 C.An international research group has developed a perovskite solar cell with strong thermal stability and enhanced electron injection by using special nanotubes made of cesium-titanium dioxide (Cs-TiO2). The scientists used titanium sheets with 99.4% purity, 1 mm thickness, and a length of 50 mm. .
