The Climate and Political Short Termism


Brexit, Trump and the potential break up of the European Union provides a "Perfect Storm" for those who have an interest in saving the planet. In the last year if a situation could get worse it did. Addressing climate change effectively requires concerted global action, compromise and sacrifices.


Global Energy and Carbon Dioxide


We started this site in 2008. At that time our younger brains wrote a few articles that provoked a measure of vitriol from the good willed and so-called green community. I say, “so-called” because their non-solutions can so often be counter productive. In the years of examining why this is, it has become my view that there is simply a lack of awareness of scale. Simply put, there is a lack of comprehension of how much bang for you buck you get with fossil fuels compared to a renewable energy source like a windmill or a heat pump. To be clear I have no issue with renewable energy sources, they are great, but thinking that we will ever meet the world’s energy needs with renewables is fanciful.


Teaching Global Warming


Our Children can’t be expected to understand the Global Warming debate until they have an understanding of “The Facts”


Confused About Energy Policy?


Could anyone explain why it is useful for UK PLC to have soaring energy prices (50% apparently) based on costly nuclear and “renewable” energy policy, such that imports from low cost carbon dependent fuel economies like China have an even greater competitive edge than they do already?


Carbon Capture

0pinion world power generation graph coal oil gas solar wind nuclear biomass

The following link by Loren Cobb from the Quaker Economist titled  “The History and Future of World Energy”, provides what I regard as one of the best graphical overviews I have seen on past present and future power generation and where it will come from. It excludes any notion of nuclear fusion but this is understandable given that it is not yet feasible! On page two of the article there is a graphical interface where you can alter the parameters changing some of the assumptions for yourself to get a different picture of the future.

One of the clear observations is that far from reducing our future dependence on fossil fuels over the nest 50 years we will in fact increase our demand. There are also sufficient reserves to continue to do this and there is a good profit for the mining companies to continue to supply this raw material to the power industry. The conclusion of the article by Loren Cobb and another one on this site is that with an increasing population and worldwide technological capability there will be an increased demand for energy over the next 50 years. And much of this will be provided by burning fossil fuels. So far from reducing carbon emissions we as a planet will be increasing them. This is inevitable.

As an alternative suggestion to reducing energy consumption and “green power generation technology” why don’t the policy makers in the world get behind carbon capture technology and pull out CO2 from the flue gasses of the power stations? Apparently 80 to 90% could be removed (wikipedia).; The main reason is probably economic since the cost of power generation would increase.

US and Chinese policy makers could force so much change here, and we are all rather at the mercy of it.
