Hanging with the lab rats: NREL researchers lay groundwork to accelerate US clean energy transition

NREL wind energy researchers contributed to a journal article published in Science on Oct. 10 that identified three key challenges for the wind energy sector: improved understanding of the resource and its flow in the atmosphere where wind plants operate; addressing the structural and system dynamics of the largest rotating machines in the world; and designing and operating wind power plants to support grid reliability.

What Will It Take to Build Offshore Wind in Oregon?

What Will It Take to Build Offshore Wind in Oregon?

The study, published this month by the National Renewable Energy Laboratory (NREL), modeled the potential cost of power from floating offshore wind farms sited at five zones equally spaced along a north-south axis at least 10 nautical miles from Oregon’s coast.

You too can model solar, wind and storage deployment

You too can model solar, wind and storage deployment

NREL uses the model to project the deployment of renewables, and now you can make your own projections, based on modeling inputs that you choose—for example, regarding the future costs of solar, wind, and storage.

Reports: Energy Secretary Rick Perry to Resign Next Month

At a Wednesday DOE event, Perry told reporters, “We're going to work with Congress and answer all their questions.” No evidence has emerged that Perry participated in Trump's effort to pressure Ukrainian leaders to investigate his political rivals, and sources told Politico that Perry’s departure was unrelated to it and had been planned for months.

Will Morrison kick off 2019 with massive own-coal?

(AAP Image/Lukas Coch) Already on the nose, could Prime Minister Scott Morrison and Energy Minister Angus Taylor do anything possibly more unpopular than announce funding for new expensive, unreliable and high-polluting coal-fired power plants during a record-breaking heatwave?

Coal units cut out as report warns ‘HELE’ plants “just as unreliable”

Coal units cut out as report warns ‘HELE’ plants “just as unreliable”

The timing is poor for market operator AEMO, which – faced with temperatures in the high 30°Cs for the coming few days – is forecasting a ‘Lack of Reserve level 2’ (LOR2) for Thursday afternoon in Victoria and South Australia.

Finding Solutions to Avoid Wind Energy Waste

The study, led by the University of Colorado Boulder in collaboration with the University of Denver (DU) and the National Renewable Energy Laboratory (NREL), combines legal and economic analysis with atmospheric modeling to demonstrate that wake effects — which occur when groups of turbines reduce wind speed for up to several miles behind them — are measurable and predictable, yet remain largely unaccounted for in current U.S. property law.

Solar power’s greatest challenge was discovered 10 years ago. It looks like a duck.

Work by NREL and others has promoted the economics, saying hey, if you ramp your plant an extra 10 points per day, yeah, it’s going to impose a little bit of extra cycling cost, but the benefit of avoided curtailment vastly outweighs those costs.
