The main task is to stop wasting it, irrespective of what type or source, if for no other reason – it costs money.
I will consider just the two main energy sources, Electricity and Gas, under this heading. Other forms are covered elsewhere.
Two things to bear in mind. Firstly –
a) Common charging elements within electricity bills for business
b) Common charging elements for gas bills for business
The second is the generation born over the past five years who will be conducting their lives in a technological era. In addition their drive to innovate will accelerate beyond our comprehension compared with what we have seen over the past 50 years.
I believe that in the next 50 years, we will have safely harnessed the energy within the mantle of our planet and that new sources of energy will have been sourced with or from the chemical elements know and some yet to be discovered.
It is therefore my view that our reliance on fossil fuels will start to wain in the next 5 to 10 years. With this in mind long term energy investment must retain the ability to change existing and implement new technology quickly and with minimum cost.
