Energy Production
Both Nuclear and Solar are almost 'free' engergy sources for using current technologies. They are safe and once the initial investment has been made, they will continue to provide very cheap energy for generations. Following CST planning model, the 'cost' of the initial investments are nullified by the boost to our economy.
Nuclear
Using new designs of Thorium based power reactors. These are safe as they do not need pressurised containment. And Thorium produces just a tiny fraction of the reactive waste. Thorium is cheaper than Uranium, it doesn't need to be enriched before use, there is a lot more of it and is more efficient as a nuclear fuel. (the only reason we don't use it in most reactors is because we wanted to produce plutonium for bombs).

Solar
Getting more efficient all the time. Just waiting to be tapped in many dwellings, businesses and in larger solar farms right across britain. The 'extra' energy produced during the day can be converted into hydrogen in locally based facilities. Hydrogen can then be used as a transportable fuel, turned into other fuels (such as Ammonia for use in vehicles).
