We get a solid amount of…interesting…. email from clean tech doubters and outright haters. We recently launched a “Letters to the editor” section, and well, I decided to run a smattering of the commentary that CleanTechnica receives (slash have to deal with) on the daily, just for your entertainment. Enjoy. … [continued]
Since the early 2000s, wind turbines have grown in size — in both height and blade lengths — and generate more energy. What’s driving this growth? Let’s take a closer look. Hub Height A wind turbine’s hub height is the distance from the ground to the middle of the turbine’s … [continued]
One windy day, I decided to go see the Østerild wind turbine test site, where the largest wind turbine prototypes from Siemens Gamesa, Vestas, MHI Vestas, Envision, and Haliade are being tested before primetime.
Floating offshore wind turbines are something of a rarity these days, but a proposed new 11-turbine wind farm indicates they are poised to go mainstream.
The Earth is rapidly approaching 1.5°C global warming, air pollution kills over 7 million people worldwide each year, and diminishing fossil fuel resources portend social instability. Yet, recently, world leaders at the United Nations Madrid climate talks failed to agree on a path forward. The core of the problem is the belief by some leaders that solving global warming will be expensive and drain the economy of their country. However, new research indicates that this belief is incorrect.
Wind covering Delaware is like the patch of solar panels in the Sahara. All primary energy will be supplied by renewable sources in a few decades. Petroleum, coal and natural gas won’t be used as primary energy sources except in rare and tiny cases.
Researchers at Stanford have discovered that directing the wake of one wind turbine away from others can boost the output of a wind farm substantially.
Coal and nuclear power are both dying, falling victim to natural gas and renewable energy. Trump used to blame the Democrats, and especially “Obama’s war on coal.” He used to take the position that removing subsidies for renewable power would be sufficient to bring a renaissance to the coal industry. But despite his efforts, coal plants have just kept closing.
Wind energy is both a clean alternative to the fossil fuels driving the climate crisis and an engine for job creation across the US – it’s a virtual smorgasbord of sustainable awesomeness.
A new report on renewables across the last decade points to real progress toward a clean energy future.
