Euroviews. View: Solar energy is cheap, fast and infinitely available, why are we not using more of it?
"We have still barely even scratched the surface of solar’s true potential to revolutionise the global power system," says Dr Harald Överholm.Dr Harald Överholm is the founder and CEO of Alight, one of the EU’s leading corporate solar providers. He is also a former member of the International Energy Agency’s PVPS workgroup on solar business models. Here he gives us his take on why he thinks solar is the best renewable source of power we have at our disposal.
It is clear that the energy transition is underway and moving at a positive trajectory.
Our future will be driven forward by an almost 100 per cent mix of solar and wind energy coupled with battery storage - with rapid further electrification of transport and heating too.
I can confidently say that this vision is perfectly feasible within the next decade. And what’s more, this future will have a very low CO2 footprint and usher in a new era of energy security and independence.
One thing that is important to point out is that short-term compromises need to be accepted in order to achieve this long-term vision and endpoint.
Nuclear and hydrogen are important - but not the best optionsFor one, we should retain existing nuclear plants until they are no longer necessary, but let’s also not allow the nuclear industry to have the power source relabelled as renewable, resilient or green, it’s not - so let’s not fool ourselves.
Nuclear bears environmental and safety risks and encourages a dangerous reliance on a handful of centralised power plants. A further nuclear build-out would be a distraction insofar as it would suck in resources required to build our renewables-based future, while not providing a reliable way of generating more power within any relevant timeframe.
A similar distraction is hydrogen. It will play a niche role in coming years, such as in the production of fertiliser, and complex industrial processes, but we must not mistake hydrogen for a viable mass-power alternative.
