Each town will have between 5, 000 and 20, 000 properties and must be "zero-carbon" overall.
The chancellor did indicate that the government would come forward with a plan for zero-carbon homes by May.
Near-zero-carbon nuclear power is popular with conservatives, while unproven CCS is meant to seduce the many coal states.
Supporters of nuclear power say reactors provide reliable, zero-carbon-emission energy the country needs to avoid dependency on natural gas.

The government announced that the city would be zero-carbon, powered entirely by renewable energy, car-free, and produce net-zero waste.
Finland aims to complete 10 successful low or zero-carbon developments similar to Low2No in the five years after Low2No is complete.
The Lib Dem proposals would include a five-year plan to insulate every school and hospital, subsidies for home energy efficiency, 40, 000 new zero-carbon homes, improvements to rail lines and 700 new train carriages.
Bid organisers said that all the stadiums will be climate-controlled and zero-carbon emitting to combat what could be temperatures as high as 50C during the two hottest months of the year in Qatar.
But currently fewer than one in 200 British homes would qualify as zero-carbon, so in order to bring major reductions in domestic greenhouse gas emissions, the government has to tackle existing homes too.
Clearly, though, the Bloom Box is still not a zero emissions tech and would only cut emissions by roughly 50% relative to the national average, unless it runs on landfill gas or biogas or hydrogen from electrolysis fueled by zero-carbon electricity (which would be much more expensive as you have to add cost of electrolysis unit, higher cost electricity, and about 30% conversion losses in electrolysis).

In a quiet cul-de-sac on the university campus, there are six experimental carbon-zero houses .
Its lead in hybrid technology is under threat as other big carmakers scramble to bring low- and zero-emission vehicles to market before low-carbon legislation bites.
Owning our own zero carbon electricity generation is a robust long-term financial strategy as well as a values-driven sustainability strategy.
The letter, organized by Beyond Zero Emissions, comes as a response to the failure of the much-compromised Carbon Pollution Reduction Scheme (CPRS), which was pilloried as a giveaway to fossil fuel industries and ineffective for driving clean energy deployment.
FutureGen would be a near zero-emissions plant that converted coal into hydrogen, to power electric turbines, and carbon dioxide, to be pumped underground.
The carbon-fibre battery monocoque is, in addition, conceived as a "zero intrusion cell" in order to meet the very highest expectations in terms of crash safety.
ENGADGET: Visualized: Mercedes-Benz SLS AMG E-Cell bares all
Long-term regulations were needed to phase out carbon emissions in key areas - by reducing vehicle emissions and work towards "a zero-emission vehicle standard across Europe".
We're now on track to go from zero -- zero commercial-scale biofuel refineries to 19 by the year 2012, and from no commercial-scale power plants operating carbon capture to five by the year 2015.
