Drivers of the Renewable Energy Future

Stefan GsangerIn 2021, almost 100GW of wind power capacity was installed around the world. In almost every country, wind power is today one of the pillars of the power supply strategy. This new record of wind power installations is astonishing and part of a broader trend – other renewables, in particular solar power, have also set new records.

Build Them at Sea, New Energy for the World

Chris WestraThe year 2022 marks the 50th anniversary of my involvement in the development of wind power for generating electricity. During those 50 years, I did a lot of research on many aspects of implementing wind energy and wrote many research reports, brochures and books on the subject. Recently I have published my second book on offshore wind energy, Build Them at Sea, New Energy for the World, for a broad audience to introduce them to this important energy source for a sustainable future. I describe the policy, (technical) developments, construction, maintenance, and the vessels used and developed for this purpose. While writing, I concluded that in the coming years, we are going to make great steps: large wind turbines of 20MW, as high as the Eiffel Tower, new installation and maintenance vessels, drones for inspections, and robotised maintenance. But even more important is the development of floating turbines and the offshore production of hydrogen at sea. Competition for the most robust and cost-efficient floating design is ongoing and development of electrolysers is fast. With all of this progress, offshore wind energy is going to become the largest potential energy source.

India: In Its March Towards a Green Decade

jhIndia has been at the forefront of the harnessing of renewable energy from the very beginning, long before climate change concerns began to be voiced. It is the momentum and experience gained in these early years that has enabled the country to launch one of the largest and most intensive renewable energy programmes. Policymakers have announced as much as 450GW of renewable energy capacity by 2026, while it is around 100GW at the moment. Thus we should see more than a quadrupling of renewable energy capacity in the country in the next five years. No doubt there are initial problems to be overcome in pushing such a large programme with regard to land, resources, technology, and many other logistics, financing and related issues.

Together We Must Act Faster!

Stefan GsangerThe latest Intergovernmental Panel on Climate Change report, published in August, leaves no doubt about what needs to be done: ‘… limiting human-induced global warming to a specific level requires limiting cumulative CO2 emissions, reaching at least net zero CO2 emissions, along with strong reductions in other greenhouse gas emissions.’ This statement clearly underscores the urgency of stopping fossil fuel burning and switching to renewable energy, including wind power, around the world.

Wind O&M – the Need for a Collaborative Approach in the Supply Chain

Gordon MAs the wind industry matures and a growing number of wind turbines reach obsolescence, the industry needs to work collaboratively to make assets more efficient, tackle new challenges and create sustainability in the O&M supply chain.
