Clean Coal and Other Energy Sources
Monday, May 5th, 2008There has been a mixed bag of reactions to the Australian Prime Minister Kevin Rudd’ discussions about coal sales to China, clean coal and what some people are calling the hypocrisy of our mining and selling coal to China.
I agree that the entire world needs to move completely away from fossil fuels but I am also a pragmatist and I realise the size of the industry here and the huge damage it would do to our economy if we suddenly stopped so I believe that the coal industry’s research efforts into developing clean ways to use coal make sense. And selling these technologies to China along with the coal also makes sense.
I know this makes some people very angry and someone recently said to me “clean coal – I’d like to see that!” The problem with being angry about something is that the people who are angry stop communicating and only tell. Unless the dialogue is two way, there is no communication and the differing viewpoints never meet to find the best outcome. It is a bit like swimming in a rip – fight it and you drown.
I believe we need a mix of energy sources and would like to see large scale development of solar because we have so much sun in Australia and especially at times when demand for air-conditioning is greatest. Our small scale domestic solar installations are very expensive to install and while great for the environment are out of the reach of most people.
The USA are installing very large scale and economic solar plants to power entire towns in Arizona and the large scale technology has been in use in California since the 198s and is well tested and reliable. There is a process using huge amounts of salt that can store the solar heat to enable the power generation around the clock.
When wind, wave, solar and geothermal energy is in mainstream use and alternative technologies are developed and economically viable together with attitudes and behavioural change we will able to reduce our energy use without much changing out quality of life. At that time the cost of coal and oil will rise to become uneconomical unless they can be audited as having worked out how to effective reduce their emissions. Their incentive will be the cost of their carbon emissions.
There are other very exciting new technologies emerging for retrofitting established buildings to make them energy efficient. I suspect there needs to be support to get these out into more visible demonstration sites.
Developing these technologies, including clean coal, and reducing dependence on coal and oil requires a national and global vision plus implementation and incentives.
Humans are very good at change and adaptation when they know their backs are against the wall but the problem is they do not all recognise the need for action now.
