Solar and wind still lead generating capacity additions

Solar and wind still lead generating capacity additions

Future growth could slow if Build Back Better fails to pass.
GE to produce zero waste wind turbine blades by 2030, company says

GE to produce zero waste wind turbine blades by 2030, company says

The plan will be carried out by LM Wind Power, a GE Renewable Energy subsidiary, which will aim to deliver no excess manufacturing materials and packaging to landfills and incineration without energy recovery.
Renewables are 87% of new U.S. generating capacity so far this year

Renewables are 87% of new U.S. generating capacity so far this year

Through the first three quarters of 2021, renewables made up almost all of new generating capacity in the U.S.
Finer System Level Details for the Comparison of Photovoltaic Technologies

Finer System Level Details for the Comparison of Photovoltaic Technologies

In our last article "Metrics for Thin Film Solar CIGS Company Comparisons," we alluded to finer system level details in the comparison of photovoltaic (PV) technologies and promised this follow up article on the subject.
National Electric Rate Comparisons

National Electric Rate Comparisons

Where can I find local and national electrical rate statistics? Specifically, I'm interested in the figures for average annual rate increases to help calculate the payback on renewable energy systems. Is anyone collecting this information? -- Alana N., Mount Vernon, WA
Fab support by simulation and scenario comparison

Fab support by simulation and scenario comparison

Simple short-cut calculations are difficult for capacity check of facilities in the event of changes in production (e.g., capacity increase, new technologies, new chemicals), due to the mutual influence of several facility systems. Only a full software-based calculation model provides enough stability for thorough case studies.
Presidential Candidates Weigh in on Energy Policy

Presidential Candidates Weigh in on Energy Policy

The League of Conservation Voters has published a comparison of the energy policy positions of the 2008 presidential candidates, which range from environmentally responsible to business-as-usual. What is startling about the comparison, however, is that some of the candidates officially hold no articulated position on a subject on which some other presidential hopefuls have gone to the wall.
Fish Passage: Hydropower Operations Reduce Bull Trout Entrainment Mortality at Tieton Dam

Fish Passage: Hydropower Operations Reduce Bull Trout Entrainment Mortality at Tieton Dam

A comparison of downstream fish passage conditions before and after the installation of hydropower turbines at Tieton Dam shows a 45 percent survival rate increase.
Metrics for thin-film solar CIGS company comparisons

Metrics for thin-film solar CIGS company comparisons

Joseph McCabe, solar industry veteran, often gets the question, “which CIGS company is going to emerge as winner in the race towards high efficiency thin film PVs?” First Solar has set the benchmarks, and newer companies are coming up with new ways to do thin film CIGS PV.
Green goals for heavy industries in the energy transition

Green goals for heavy industries in the energy transition

We have looked at the impacts of three of the most ‘hard-to-abate’ sectors and what alternatives may look like from the perspective of their emissions, costs and practicalities.
