When wind turbine blades are decommissioned they are usually scrapped and thrown into landfill because they cannot be recycled. In the U.S. over the next four years alone that will be the fate of more than 8,000 blades. As wind installations increase so will that number. It's because most blades are constructed from epoxy or other thermoset resins. So National Renewable Energy Laboratory (NREL) researchers are using a thermoplastic resin, … [Read more...]
U.S.: Counting Renewables jobs and projects under threat, what can be done and why
All sectors across all economies are trying to add up their potential job losses and projects in jeopardy, then telling their governments to prioritise them for support. Mike Jacobs at the Union of Concerned Scientists looks at renewables in the U.S. He quotes news reports that over 100,000 workers in this fast-growing industry filed for unemployment in March 2020. On top of that, the already planned expiry and phase-down of certain targeted … [Read more...]
Modelling total costs for Onshore Wind power plants: from site prep to grid connection
The costs of wind turbines is dropping. But that means all the other capital costs - site preparation, foundations, infrastructure, tower construction – will become a bigger part of the total. In the U.S. they currently account for around 30% of the capital expenditures needed to install a land-based wind plant. To keep those costs under control the National Renewable Energy Laboratory (NREL) has created a comprehensive open-source modelling … [Read more...]
