A Short Series Exploring Tough Questions about Old Houses and Energy Efficiency
...as alluring as renewable energy may be, the fact remains it makes very little sense to slap solar panels or a wind turbine on a home or building that has not been first retrofitted for improved energy performance. That’s basically like cranking up your super-efficient heating system and keeping all the windows open in the dead of winter – you’re missing out on the real emissions reductions. But assuming reasonable steps have been taken to improve efficiencies, renewables can – and will increasingly– make a lot of sense.
Financially, renewable energy sources may not pencil out often now, but as energy prices go up and manufacturing efficiencies improve, they are likely to be more attractive to homeowners. I suspect we’re in for more conflicts between home and building owners who want to install renewables in visible locations and preservation commissions who believe this is inconsistent with preservation standards. As I see it, the integration of renewables into historic homes and neighborhoods is one of the most crucial issues within the sustainability and preservation arena. It is a test of our abilities to embrace the need for buildings and communities to evolve over time to meet current needs and align with modern-day values.
The reality is, renewables will be an essential part of our future. And we need to get used to it. Outside this country, the European Union has set the target of getting 20% of their energy from renewable resources by 2020. Even China, no bastion of environmental responsibility, has set their sights on 15% renewables by 2020. In the U.S., the Waxman-Markey Climate Bill, which passed the House early last summer, set U.S. targets of 20% renewable energy production by 2020 (though the Senate never passed their version of a climate bill and the fate of future climate legislation is uncertain in this Congress.) It’s worth noting, however, that some states have already set their own targets in the absence of federal action. California is among the most aggressive with the goal of getting 33% of its energy from renewable sources by 2020.
