Good to hear that leadership is waking up, in spite of the best efforts of Yergin and Lynch. The real test will be what near term changes in policy will be taken.
And he referred to the problem as security of fossil fuel supply, so that also includes natural gas, though not explicitly addressed in the quotes above.
Interestingly enough, building heat energy is within the grasp of the EU, just requiring a recognition of seasonal borehole energy storage of solar energy, in pronounced overabundance in solar thermal collectors during spring, fall, and especially summer. Indeed, most people with solar hot water heaters don't know what to do with all the excess heat during the summer, so either the valuable energy is bled off through an overtemp valve, or installers put in undersized systems that have inadequate winter performance.
Note that an entire neighborhood is being heated by season solar energy storage in boreholes in Canada near Calgary.
Your link to the Canadian village seems to be corrupted. At least, it does not work on my computer.
Here's the link to the solar heated Canadian village, Drake's Landing.
Col. Drake started this oil thing in Pennsylvania a century and a half ago. Now Drake's Landing using solar heat all winter long, and my efforts...
Best Hopes for the Drakes,
Alan Drake :-)
Storage of solar thermal energy can save a lot of fossil energy over time. A heat pump system could be designed in U.S. homes to store thermal energy during the summer and use that heat during the winter. The heat pump runs more efficiently during the summer and winter saving natural gas and electricity. Using solar thermal collectors, absorption cooling and a fluid source heat pump, most U.S. homes could save a significant amount of money and save a lot of fossil energy every year.
The Drake's Landing solar thermal system would use less energy then the heat pump system for general operation,
Heat pumps still use about 1/4 to 1/6 of the energy to move the energy, but when we reach a point where the grids are extremely expensive, and/or are down more then they are operating, the heat pump system turns into a loss of money, as it would use too much aucillary power to operate.
Or, let's not use ANY external energy to heat and cool. Still have to find a solution for your lights, water and cooking, but that should be simple enough...

The problem with these homes? They don't fit into the budget of about 99% of the planet. I do believe people are going to be stealing the concept, though, if the company doesn't make it more readily available.
Brilliant design, all said. My question is whether you can get similar results with logs, natural or hewn?
Cheers
I have heard that argument before, but if your heat store gets down to 80F in February, you do not have much heating without a heat pump. Lots of people live where they have all electric homes and use heat pumps for heating and cooling. The heat pump is more efficient working with 60F fluid than 100F air when cooling. It is also more efficient using 80F fluid for heating than using 30F air. If you have PV panels offsetting the electricity usage, you can do quite well. Solar absorption cooling can take care of a lot of the cooling in many parts of the country and can offset a lot of compression cooling costs during the day. A systems approach needs to provide benefits in more places than Alberta or Phoenix.
We'll know for sure soon but it looks like a 15% of all energy from renewables by 2020 target will be set for the UK.
