If any evidence is needed that our way of life needs drastic change, look no further than the current state of affairs with energy supplies in the UK. Not only have we made our country dependent on foreign fuel supplies, the sources include some of the worst regimes on the planet, such as Russia and Saudi Arabia. Furthermore, we continue to burn fossil fuels at an alarming rate. Meanwhile, even though we have an abundance of renewable energy sources, we have not yet tapped their full potential and we have failed to build the energy storage systems which can be used to soak up the surplus renewables. Meanwhile we are becoming increasingly reliant on imported electricity, produced in the Single Market. That significantly weakens our negotiating position with the EU. They can simply flip a switch to turn off the UK's power. Meanwhile, we are heavily dependent on imported natural gas so an international shock to demand, supply and price hits us hard back in the UK.
Our dependency on foreign food and energy supplies is a national security risk. We have to aim to be far more self-sufficient. And that will probably mean changing our lifestyles, as I know from personal experience.
