What do I think, What can I do?

The wind is more powerful and constant in the sea. In fact, it has been used for many centuries to cross the oceans by brave sailors who knew quite well how to find favourable winds. But moving ships is one thing and harvesting wind cost-effectively another different one. I have always had doubts about off-shore wind power to become an important energy source because harvesting energy in ocean conditions is more difficult and transportation is an additional cost. But the data are telling me I was not right.

Last year, 2018, was not so good for climate change. However Europe installled 2,6 GW of new off-shore wind power, as shown in WindEurope statistic data. This is an increment of 18% in off-shore wind power capacity in 15 new parks. Quite good numbers that show a steady growing trend. UK plans to have 25 GW in 2030 and Germany 20 GW. Other countries (Poland, France, Belgium) in Europe also have plans. Europe has been leading this technology but in USA there are many projects currently and China is starting too.

Some concrete examples are:

  • The project called Gemini Wind park will be the first and important step to transform Duch fossil power generation into renewables and it is starting to be built.
  • Hywind in Scotland is quite special as it is a floating off-shore, for the moment floating off-shore is quite expensive compared to fixed one but it has a huge potential and it is expected to get cheaper.
  • Gode Wind 1 y 2 in Germany with more than 500 MW of power.
  • The news about the first off-shore wind power auction that did not need any subsidy was great and really significant although it has to be qualified as explained in the German post Germany to get free offshore wind! Wait, what?.

In this moment off-shore wind only represents 2% of electricity production in Europe, less in other important economies, but it is growing and growing steadily. The technology is becoming competitive and the resource is vast. Moreover, it is and opportunity for oil companies to “recycle” their activity. In my opinion this is good because it can soften the transition if some of the greatest losers (oil companies) get some compensation and besides their experience can be helpful for deploying off-shore wind and this can help reduce costs and times faster. Getting new renewable and competitive electricity sources is very important, it helps in the fast transition we need and diversification will help in the intermittency problem.

Even more, these examples and data were all about the “fixed” off-shore wind, however the floating wind mills would allow a further development, more wind in different locations and another jump.
