www.vox.com/2016/4/5/11347962/net-powerI have always been skeptical about carbon capture and sequestration at fossil-fueled power plants. It's not so much the technological barriers — they are serious, though not insurmountable — but the cost. Fossil fuel power plants have steadily gotten more efficient, but the problem is, no matter how efficient your plant is, capturing the carbon dioxide emissions involves bolting on a second facility to process and separate the waste gases. That second facility requires power (it's a "parasitic load," cutting into efficiency), and it adds to capital costs. Coal and natural gas are already losing out to wind in many areas, without sequestration. Once you add sequestration, even as wind and solar are getting cheaper and cheaper, how can fossil fuels with CCS possibly compete? And that is the entire reason - make the fossil fuel plants uncompetitive. I expect a rush to try to put all these regulations in place before it becomes obvious to all that temperatures are on the way down. I would not want to be a known climate 'scientist' in 5 years time. Colder and grid failures due to politically inspired decisions on power generation using the climate 'scientist' reports. Expect the climate 'scientists' to be thrown under the bus by politicians who will of course retain the taxes and powers that they rushed to put in place.

The problem with Solar and Wind are they are intermittent. Winds big problem is variability, too low - no power, to fast shut it down so it doesn't fly apart. Speed of the wind changes power changes, so load leveling is a problem. Solar power only when the Sun shines. Also variable because of clouds and time of year (hours of daylight changes). So the two biggest problems are load leveling and energy storage to carry you thru periods of no wind or too much wind and for solar the amount of daylight changes every day due to clouds and time of the year. The big hold up then is the cost of energy storage not so much as the cost to produce energy under ideal conditions.

It has suddenly dawned on even the slow UK MPs that their attempt to 'out-green' other countries set in train a cockup of huge proportions and that it is now too late to do anything about it. This at a time when as Theo has pointed out reliable power supplies are going to be essential. There is just 0.1 per cent spare electricity in the current system, a dangerously small amount of headroom in case of emergencies over the winter months, the report warned.
It cost the National Grid 800 times more than the standard price to buy additional power to cope with potential shortages in 2015. In total the company will spend £122.4 million on emergency power this winter and costs are expected to rise in 2016/17.www.telegraph.co.uk/news/2016/12/19/electricity-bills-set-rise-30-year-power-rationed-amid-shortage/Heavy snow followed by a hard freeze with a stable anticyclone with no wind, and the UK will be experiencing rolling power cuts. As the UK has insisted on 'Smart Meters' the attempt will be made to hide these power cuts by only removing power from every 37th house or closing down their high demand devices like refrigerators, washing machines and dishwashers. Whereas if it were a just system those voters registered as 'Greens' and all politicians (House of Commons, offices and homes) should have their power removed first and restored last.

Surge protection just got a workout. Hope nothing fried.

Surge protection just got a workout. Hope nothing fried. Living in one of the areas of the world with the highest number of lightning strikes I have a 'whole house' surge protector and every electronic device in the house is powered indirectly through battery backup - so a lighting strike on a palm 15 feet from the house only killed the sprinkler pumps. What causes the surge in the frigid Dakotas Sig?

When the grid is trying to balance because of the wind surges we will get fast drop out drop in cycles. ND has enough wind power now that it screws the grid up.

Looks like the subsidy farmers are going to experience a harvest failure.... "Energy bills to fall as billions in 'green crap' subsidies axed: Ministers unveil plans to reduce money given to wind and solar energy firms Billions of pounds of subsidies for the wind and solar energy industry are to be cancelled The move was announced as part of Theresa May's new industrial strategy She said green subsidies should be slashed to help steel plants compete abroad"www.dailymail.co.uk/news/article-4150244/Billions-wind-solar-subsidies-axed.htmlNow to see how rapidly the shining examples of renewable energy that each can power a small town (or so the glossy brochures tell us), become rusting abandoned monuments to politicians conned by venal 'greens'.
