Energy Storage Solution for the UK: Large Scale Pumped-Storage Site
energy storage in UK
Most people have assumed that the UK does not have enough feasible pumped-storage potential for a renewable energy revolution to take place. Intermittency is the biggest challenge for wind energy in the UK.[read more]
Wind Power Isn’t Perfect, But It’s a Hell of a Lot Better than the Alternatives

If we were to stick with our coal phase-out strategy without wind, we would need to burn more natural gas. The reality is that when the wind blows it gives us the opportunity to burn less natural gas when it’s being used to displace coal. This is partially why greenhouse-gas emissions associated with electricity generation in Ontario have fallen by two-thirds since 2003.[read more]
Energy Storage Systems Finally Getting The Attention They Deserve

The renewable energy industry has been growing by leaps and bounds in recent years. More wind and solar power is contributing to the electric grid than ever before. There is one drawback to renewable energy sources however, and that is their intermittent periods of production and disruption. After all, the weather does...[read more]
Texas' Record Electricity Demand Creates Battling Headlines about Wind Power
Last Wednesday, August 3rd, saw a new record set in the ERCOT electricity service area. ERCOT wasted no time in putting some data from these events online. The American Wind Energy Association (AWEA), put up a blog post titled Wind helps meet new Texas record for electricity demand. Now, that's something we would expect, except for...[read more]
Clean Renewables and Clean Energy Storage – A Perfect Combination of Domestic Resources
There are interesting synergies between renewable energy and energy storage that have profound implications for the Smart Grid and our energy and economic security. Wind and solar are readily available domestic sources of clean renewable electricity and share a common characteristic of intermittency. Wind tends to pick up at...[read more]
Do wind-gas generating systems prevent CO2 in high wind penetration environments?
Two Carnegie Mellon University researchers, Warren Katzenstein and Jay Apt recently looked at the question of how the intermittency of wind and solar effected CO2 emissions from the grid. (see Air Emissions Due To Wind And Solar Power, Environ. Sci. Technol., 2009, 43 (2), pp 253–258). They found that variable renewables decreased...[read more]

“"....and introduce real competition into a fuel market ...."What prevents someone from creating and selling a competitive fuel for less?Does someone need to grant permission to do so? Is not the ability to make a lot of money by creating such a fuel not adequate in itself?And are you serioulsy suggesting there are enough arable acres of ground in the US to grow all the fuel industry ...”
“It is a false argument to compare to the USA experience: their reductions are caused by the switch to gas thanks to the present abundance of shale gas.Regarding the ETS: Don't blame the hammer for being a bad screwdriver! The ETS is doing exactly what you can expect from a cap-and-trade program. It decreases carbon emission following exactly the planned trajectory, for the lowest costs possible ...”
