Wind and solar are now cheaper than fossil fuels

For years, grid parity – the time when solar and wind would be cost-competitive with fossil fuels and nuclear – was the holy grail of renewables energy, a target to reach in a distant future. But the future is now. 

Was it Obama’s “moon shot speech” ?

The State of the Union speech given yesterday by President Barack Obama might well stay in the History books like John Fitzgerald Kennedy moon shot speech that sent Americans on the moon in less than a decade. Indeed President Obama asked for 80% of America’s electricity from ‘clean energy’ by 2035 (including clean coal and… Continue reading Was it Obama’s “moon shot speech” ?

10 energy myths, debunked

We have heard that before : ” Wind power is far too unreliable ” or ” Nuclear power isn’t a safe solution “. Yet the reality is most of the times far from these myths. Popular Mechanics published a long article debunking energy myths. I wrote about some of them such as clean coal that… Continue reading 10 energy myths, debunked

IEA believes carbon capture and storage is crucial

The International Energy Agency recently released a report on how carbon capture and storage (CCS) could account for 19 percent of the greenhouse gases emissions cuts needed by 2050. The IEA specialists believe Mankind would need to install up to 3,000 plants by 2050. This however might prove to be a problem as CCS is… Continue reading IEA believes carbon capture and storage is crucial

Carbon Capture and Storage works !

Alstom and various US partners have been testing carbon capture on a small Wisconsin coal-fired plant. After a year of testing, this pilot project is a success as 90 percent of carbon dioxide was captured. The French company is willing to commercialize CCS for new and existing coal fired plants as early as 2015. But… Continue reading Carbon Capture and Storage works !

More on the UK Low Carbon Transition Plan

My post on the UK Low Carbon Transition Plan in July was short, way too short for such a news as a major economy is committing itself to cut its greenhouse gases emissions by 34 percent by 2020 compared to 1990 levels. Using all means at its disposal – energy efficiency, renewables, nuclear, electric cars,… Continue reading More on the UK Low Carbon Transition Plan

Can IGCC clean up coal ?

I was wondering if we as Mankind could clean up coal and if it was worth the hassle. Indeed, Carbon Capture and Storage seems promising but is too little too late to solve our climate change problems. To an article on the New York Times, an alternative to CCS could drastically cut greenhouse gases emissions… Continue reading Can IGCC clean up coal ?

Can we clean up coal ? Is it worth the hassle ?

To a study from the Massachussets Institute of Technology : “There is today no credible pathway towards stringent GHG stabilization targets without CO2 emissions reduction for existing coal power plants.” To me retrofitting coal-fired plants represents a huge detour from going straight to massive plans of energy efficiency and low carbon energy alternatives like wind,… Continue reading Can we clean up coal ? Is it worth the hassle ?

Why CCS won’t solve the climate change problem

The French magazine Science et Vie published this month a most interesting article on why Carbon Capture and Storage (CCS) won’t be able to deliver all its promises of mitigating climate change. Indeed to many international scientific experts putting carbon to the ground is too risky, too expansive, too little and… too late ! This… Continue reading Why CCS won’t solve the climate change problem

Why clean coal is nowhere near happening

Some are trying to convince the public that clean coal is the ultimate solution to all our needs. Even if I already stated my opinion on what I consider as the panacea, I will rebut their arguments. Clean Technica outlined no less than five reasons why clean coal will never happen, or if it would… Continue reading Why clean coal is nowhere near happening

More and more tests of Carbon Capture and Storage

Carbon Capture and Storage (CCS) is one of the main solutions to decrease the greenhouse gases emissions of coal-fired plants. However there is no commercial application yet, but several programs are on their way in North America, Europe or China. The oil-producing countries from the OPEC also plan to work on this technology as it… Continue reading More and more tests of Carbon Capture and Storage
