We're almost at the end of the first month of the Volkswagen scandal, which now includes 11 million cars and Leonardo DiCaprio. VW's US boss has testified to Congress, blaming a few rogue software engineers. All the while, questions have raged about VW Group's future: which projects are safe, which ones are on the chopping block, and how exactly will the company recover from this?
...
VW's board has finally started to answer some of those swirling questions. For starters, there's going to be much more emphasis on electrification. Electric vehicles and hybrids have played more of a bit part at VW, compared to Toyota, GM, and domestic rivals BMW and Mercedes-Benz. That's going to change with a standard electric architecture that can be used across multiple vehicles and brands.VW Group isn't devoid of hybrid and EV know-how. Audi's Le Mans program has taught it a lot about high voltage automotive systems, and Porsche has a wealth of experience from the 918 Spyder, Panamera Hybrid, and even the 919 Hybrid racer. VW would be smart to leverage all these programs.
VW is the largest car company in Europe. This is what sudden, disruptive technological change looks like.

Not to diminish your point, but it seems to me that the elephant in the room with regard to "green" energy sources is the task of heating buildings during the winter. Here we are talking about energy consumed in the form of metered electricity and fuel for vehicles. In my case, both of these things combined are less than the energy used to heat my house.

Good insulation and a ground source heat pump will get you there. Radiant floor panels instead of forced air or radiators make it even better, and when you first experience them on a winter day you'll think you've died and gone to heaven. People who use GSHP's regularly report trading heating bills of thousands of dollars for an electricity bill of $100 for the entire winter. If you have solar panels, then you wouldn't even have that. Unless your house sits directly on a rock slab, you can use either the column- or trench method to sink your heating loop, depending on how much subsoil you have.

Insulation, and new windows. Almost any home can be bricked. Any home with an attic can probably take some additional insulation, unless you've already filled it to the rafters.
We really need now construction methods that are inherently more energy efficient. Typical walls in the US are about 6 inches thick. Thicker walls, with more dead air space goes a long way toward insulation. There's little reason that your exterior walls can't be a foot or more thick. Concrete slabs are usually poured on the ground. Digging down a couple feet, then putting styrofoam on the ground, and finally using concrete with air mixed in will reduce energy consumption even more. Concrete roofs capable of supporting sod, and possibly some shrubs and bushes, really reduces your energy needs.
All we need do is thing outside the box, and we can cut energy consumption far more significantly than most people think.

Exactly. The biggest bang for the buck with energy savings is insulation. Now with blown-in or spray-in insulation it's dead easy. They show up in the afternoon and a couple hours later you are good to go. Then you win in the summer and the winter. I threw in GSHP (ground source heat pump) up-thread because it's such an excellent off-grid replacement for natural gas, oil, or wood. But even if you don't do that you save tons because you simply don't have to burn as much of the stuff to get the temperature you want.
If you're building something new then a Passiv house design will save hundreds of thousands of dollars over the life of the structure ($5K * 30 years). Consider what that money would turn into if you put it into an index fund instead of handing it to Big Fossil Fuel/Big Power and you've suddenly paid for some kid's college or built a nice retirement nest egg for yourself. It would be a massive shot in the arm for the economy, too. The US spends $365 billion on oil alone every year. If we didn't do that it would be like giving the economy an American Recovery and Reinvestment Act ($800 billion)-size stimulus every other year.
