Scotland's first Climate Change Bill aims to reduce greenhouse emissions by 80% before 2050. It is one of the most ambitious targets in the world, requiring what amounts to a 3% cut every year. That cannot be achieved without shifting the existing balance between planning considerations and the wider benefits of installing green energy systems. Heating, lighting and powering our homes account for around 27% of emissions. And it makes sense to take the strain off the national grid by allowing households to generate their own power. So we welcome yesterday's proposal that would allow householders to install micro- generation systems such as solar panels without the red tape, delay and expense of obtaining planning permission, even if it merely brings Scotland into line with England.

Scotland's climate and population spread mean it is well-suited to micro-renewables (though it is fortunate clear blue skies are not a prerequisite for solar power). Since the previous administration's scheme for encouraging the installation of micro-renewable technologies was introduced in 2003, more than 2000 green pioneers have taken up grants totalling £18m. Their actions have been prompted more by concern about climate change than money, because even with grants these investments take decades, even centuries, to amortise. Simple measures such as installing loft insulation, low-energy bulbs and condensing boilers or turning off appliances offer quicker savings in both energy and cash. Though mounting oil prices tilt micro-renewables calculations the right way, the big challenge is to get the payback times down to an acceptable level.

There are several ways of doing this beyond merely increasing grant levels. Energy companies could be given incentives for encouraging customers to install micro-renewables. And there needs to be a proper system for suppliers to measure the excess energy exported to the grid and compensate those who generate it with lower bills. Under Sarah Boyack's Private Member's Bill, council tax would be cut for those generating their own power. The Shadow Environment Secretary's measure deserves consideration. Without such proactive policies, climate change targets are meaningless. Another issue that needs attention is a system to ensure the industry is supported by a skilled network of installers, as poor installation is the biggest threat to this growing sector. In social housing, micro-technologies could also help the fuel-poor to reduce their power bills and do their bit for the planet.

Micro-generation tends to cut emissions in more ways than one. Research suggests that DIY energy generators quickly acquire a grasp of energy issues and this in itself cuts their energy consumption. Many, if not most, of us are concerned about climate change, energy security and oil costs, but feel powerless to do anything about these issues. Micro-power empowers.
