Renewable energy has long broken into the mainstream and now waits patiently to step in as the supply of fossil fuels becomes increasingly precarious.
In the European Union, 2021 saw renewables reach an impressive 37 % of total electricity production. Wind and solar power have shouldered the majority of this increase, and last year these twin technologies generated more electricity than gas for the first time. This strong level of progress shows the potential is there to go even higher.
Despite recent events, the most compelling reason to wean ourselves off fossil fuels remains the climate crisis. Cop27 will provide a moment to take stock of the progress countries have so far made on cutting greenhouse gas emissions during this crucial decade for climate action. Renewable energy has never been a more relevant and urgent part of the solution.
The current progress on wind and solar power over the past 10 years would astonish the early innovators of these clean technologies. But the question now turns to how we can scale up further and faster to meet our climate targets.
Offshore wind stands out as a technology which can meet our need for new, quick-to-build, and large-scale, clean power. It is estimated that global offshore wind capacity could reach 286 gigawatts by 2030, up from 52 in 2021. This is a near sixfold increase within a decade, an astonishing figure which could provide clean energy to millions of households. But building such large amounts of renewable power is no small task. It will require high levels of investment, strong political will, and a commitment to sustainability.
Government priorities and energy policies often change at a moment’s notice, and this naturally creates uncertainty. This needs to end. Renewable projects which can take years to build are made more expensive and more complicated by an unstable policy environment.
Another element we need to change is complication. The journey from scoping out plans to getting permission to build can take an inordinately long period of time. Developers rightly have to go through different levels of assessment, from site selection to supply chains. But national governments should aim to make this process easier, clearer, and more transparent.
The other concern in a headlong rush to build new renewable energy capacity is the possible impact on nature. Ignoring this concern would run counter to caring for the planet.
Businesses also need to have the circular economy in mind when they build out renewable projects. Here it is encouraging to see the industry investigating recyclable wind turbine blades; using recycled materials in the manufacturing process; and exploring how scrap steel from old projects can be used for new wind farms.
But a positive impact requires us to go further. Everything that goes into the ground needs to be 100 % recyclable, and the ground itself needs to be 100 % restored when a project reaches the end of its life.
The sky is quite literally the limit for renewable energy. For all the progress we’ve made there remains huge untapped potential in these technologies. We should aim to be as bold and as ambitious as possible.
