Only for americans
This study really does need say it's specific to the USA, it really doesn't work elsewhere in the world.
Friends in the 'States tell me that their electricity consumption is higher in SUMMER than in winter. Air conditioning is considered a necessity and is expensive to run - a situation that simply doesn't feature in the UK or wider: in continental Europe. Given that is when solar PV is most plentiful, the american model doesn't fit a european climate.
Secondly, take a look at the power generation prediction website http://re.jrc.ec.europa.eu/pvgis/apps4/pvest.php
This allows you to click a point on the map and get an estimate of the amount of leccy a "1KW" solar array will generate. Even in the sunny south-east of the UK, you'll get on average 1kW*Hr per day per kW of installed capacity ... and on half the days, less than that! Brrrrr.
Thanks to the power company, we know that chez Pete 2 uses about 10 kW*Hrs of electricity a day. A quick peruse of last winter's gas bill shows that from October - March, we used just over 9,000 kW*Hr or 50 kW*Hr per day for heating/HW & cooking. So reckon on about 60kW*Hr of energy usage per day that would have to be supplied by solar and wind. And then let's ignore wind power as there are many windless days.
Going back to the aforementioned website and selecting Daily Radiation tells us that an average day in January will produce PV electricity for 8 hours at a maximum rate of 100W / m², or roughly 400Watt*Hours of electricity per day. Thus, we'd need 150m² of PV panels to supply our daily needs - assuming the sun shines during January. That figure would require the entire back garden to be filled with solar panels, plus a few more on the roof. Even if the PV generation is located remotely (rather than each household having their own), this would double the amount of land needed to support each house - and then more to supply industry and yet more for power conversion / storage and transmission.
Somehow, I don't think this is going to work ...
