If there is to be enough energy in the future, we must change our thinking on energy supply! Governments will probably not provide the answer.
We need to put aside our linear thinking and start thinking exponentially; so what do linear and exponential thinking mean?
If I walk outside my home and take a step of 1 metre each day, at the end of the month I will have travelled – that’s right – 31 metres. That is linear thinking.
If I walk outside my home and take a step on day 1, 2 on day 2, 4 or day 3 and so on – how many steps will I have taken after a month? It may surprise you to know that I will have travelled around the world and back 26 times! That is exponential thinking!
Some further thoughts:
Then there is storage. Not only are lithium-ion batteries coming on leaps and bounds in effectiveness, there are also new technologies that use sodium and water and a liquid metal battery which relies on heat to keep different metals liquid and exchange power between them!
So the vision long term is to provide abundant energy, store it and use it intelligently via a smart grid, energy efficient and smart controls.
Solar is expected to reach grid parity in the UK by around 2020 in the UK – much sooner in other parts of the world (equating to around £1/Wp installed = 6pkWh)
And that is just solar – not to mention wind, energy from algae, nuclear……….
In effect, we want to create an “internet” of energy supply – where is energy is abundant, cheap and democratically available.
The world is moving away from oil & gas in any case because the use of fossil based fuels is releasing carbon dioxide (CO2) into the atmosphere at a disturbing rate and causing the temperature of the planet to rise.
“The effects of climate change are now accelerating so rapidly that statistics are out of date before they are printed. Patterns of rainfall are changing, heat waves, floods, storms and droughts are all becoming more prolonged and severe. Sea levels are rising.”

While each solar project varies according to the circumstances of the individual house, community or business, there are some great benefits for all Eco2Solar customers.
With a renewable energy system you can reduce and offset your carbon emissions by up to 1 tonne per annum for an average domestic system – equivalent to a 3,500 mile flight from London to New York, or 3000 miles in a car

An average domestic renewable energy system with a peak power of 2.5kW will produce around 2,000kWh of energy per annum; but what do these terms mean in the real world?
