Miles below the Earth’s surface, there’s enough thermal energy to power all of humanity for the foreseeable future. It’s called geothermal energy, and it’s poised to play an increasingly large role as a source of always available, renewable power. Now, there are a number of startups in the geothermal space, working to figure out how to access this heat in difficult to reach geographies, at a price point that makes sense. And it’s even gotten the attention of oil and gas industry giants, who are interested in greening their portfolios while sticking to their core competencies – extracting energy resources from deep within the Earth.
In the past decade, wind power capacity has tripled, and it’s projected to double in the decades to come. Wind is now America’s top renewable source of electricity generation, and the domestic offshore industry is finally taking off, as major manufacturers debut ever larger and more powerful turbines. While the industry faces some challenges with permitting, public opposition from various interest groups, and the obvious intermittency issues, there’s no doubt that wind is poised to play a major role in the energy transition. The question is just how fast it will grow.
Searching for ways to reduce our reliance on fossil fuels, engineers and entrepreneurs are looking to a largely untapped potential source of renewable energy: wave power.
The shipping industry plays a critical role in the global economy, carrying approximately 90% of the total tonnage of world’s traded goods. Shipping propulsion has changed radically since the mid-19th century, from the renewable energy of sail power, to the coal power of steamships, to the predominance of heavy fuel oil and marine diesel oil. But renewable energy technologies could transform the global shipping fleet again, at all levels and scales.
Lookback at the highlights of the first transatlantic of Energy Observer! 5,000 nautical miles traveled in self-sufficiency thanks to renewable energy and hydrogen, bearing in mind the very specific context. A technologic and human challenge in extreme conditions which proved the performance of our embarked technologies.
