Renewables Rampant

Coal Collapses and Renewables Rise. This graph of UK electricity; part of a global trend.

At this time each year on this blog I like to highlight something that has helped in the process to make a more ecologically sustainable, socially just and peaceful future possible. Sometimes I focus on a political leader who has made an outstanding contribution, sometimes on a particular innovative clean energy technology. This year I want to celebrate a whole global trend, the switch from fossil fuels to renewables, and especially the growth of North Sea wind.

Ever since I started blogging I’ve been saying humanity should switch to 100% renewables, for electricity, heating, cooling and transport. We can then simultaneously ditch fossil fuels and nuclear. The speed with which renewable technologies are progressing is staggering. Performance is improving while costs keep tumbling. The ecological case for moving from ‘The Fossil Fuel Age’ to ‘The Solar Age’ always was strong, now it is the most economically sensible thing to do.

In 2017 the first contract has been signed which will see an offshore wind farm built without subsidies. The German electrical utility EnBW submitted a bid of Euro 0.00 in a competitive tendering process to build the 900 MW He Dreiht windfarm in the North Sea. As solar and wind energy get cheaper the case for greater international grid integration gets stronger. The Dutch grid operator TenneT has proposed building an artificial island on the Dogger Bank and linking all the electrical grids of the countries surrounding the North Sea together in a hub and spoke arrangement. Electricity could then be sent to wherever in Europe it was needed. I’ve blogged before about this, but now support seems to growing and it is projected to be in operation by about 2027. TenneT estimates that 30GW of windfarms might connect to the first hub, and that other hubs might also be built. This would be a huge step forward in reducing carbon emissions and pollution in general across much of Europe.

All over the world innumerable renewable energy projects are demonstrating that we can provide electricity, heating, cooling and transport to all 7.6 billion of us while tackling climate change and achieving all the other global goals. Over the coming year I’ll highlight more of the technologies and politicians that are showing the path to a better future.
