A Rush for Renewables

I have been using this phrase for about a year in talking to people and in newspaper comments. I want to counter that Dash for Gas. We have the possibility of a new sustainable economy where everyone can participate.

  1. Start a nation-wide project to insulate all buildings and make all new building zero-carbon. This will employ people all over the country and many people with little skill can be trained to do this work. This is really investment with a long term return in reduced power needs, better health, and a trained work force. Probably there will be a reduction in crime as well. During this process we will find people who can be trained further for ever more skilled jobs. As people in each area of the country earn more, there will be more to spend locally and new businesses will be able to grow in every town. This could start tomorrow if we made the investment. The return on investment is near immediate.
  2. I am in favour of nuclear (fission) power but this is contentious for many people and we need to regain the country’s pre-eminence in nuclear technology in order to develop new safe designs (which do exist). This is a long term project and we need to work on other zero-carbon technologies now.
    So, let’s go full ahead on solar. Solar power is clearly the future for at least the next 100 million years, after which we may need a rethink. Although people think of Britain as cloudy with short winter days, there is still enough solar energy input to power the needs of the country especially if we make energy use more effective, efficient.
  3. When solar and wind power are mentioned there are immediate objections that it is cyclical and we need power at night and in winter. This is the next issue to address. First we need to see that many things that we might want to do can also be cyclic. I cannot predict how societies will develop in the long term but, taking some evolution of how things are now, an example would be people driving to a place of work. If this used an electric car, that vehicle could be charged while parked during the day. Although there is flooding in the UK, we will also get drought and desalination of sea water could address that, being done during the daytime when solar power is at its peak. Manufacturing could be done during the day time though only in some industries. We need to be smart and flexible about how we optimize the resource just as we were before before the industrial revolution. Of course we can store energy, and that is already done for electricity to cope with surge demand by pumping water to a high reservoir and releasing it to drive a turbine generating electricity when there is a sudden peak in demand. There is a role for this mechanical storage. However, we should also be developing chemical storage as in batteries.
  4. Research and development of chemical storage technologies. This is high-tech investment. If we are to trade with other countries we need something to sell, and best to support what the world needs into the future. This research will cover hydrogen storage, fuel cells and evolution of current battery technology. I imagine that there will be a lot of distributed solar PV and therefore distributed battery storage; each building with solar PV would have its own battery storage pack. An advantage of this is that we will have a very robust and resilient power network with no big points of failure.
  5. These are not jobs that can be outsourced; insulation and solar PV installation will provide work for people in the UK for many years, and there will be ongoing maintenance and upgrades for ever. The work is distributed all over the country. We can innovate as well as anyone and make sure that there is a focus on best methods for the UK as well as looking to develop products for sustainable living globally. Each region of the world will need its own local expertise. Other new ventures will spin off from this. For example, with plentiful solar power we could do vertical farming where we grow fruits and vegetables in tall buildings using solar powered lighting in which we can make optimal use of water and control pests without pesticides. Whole new industries that we have not thought of will come into being.
