Political battles at the most local levels are slowing the pace of decarbonization Property owners in the windy and sunny parts of the U.S. are pushing back against large-scale renewable energy development, opposition that researchers say could slow the transition to a cleaner economy.

Small solar panels are to be installed on the roofs of houses in the village of Sabana Real, Dominican Republic. The local project is part of a major plan: By 2025, the country hopes to generate a quarter of its energy from renewable sources.
There’s a lot of interest in the hydrogen fuel economy. Here’s what you need to know about how it works and the hurdles it faces.
Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind. These qualities make it an attractive fuel option for transportation and electricity generation applications. It can be used in cars, in houses, for portable power, and in many more applications.
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.
