The Guardian asked a range of commentators the following questions about a green investment bank, an ideal widely talked about for the UK.

1. How should it most effectively be set up?

2. What should it use its financial resources to support?

My response was

1, The German state investment bank KfW is an attractive model. This entity lent €60bn last year, almost half of which went to companies involved in environmental protection of one form or another. It raises money on the international capital markets but its conservative policies and long-term perspective have meant it has been able to continue supporting smaller companies and environmental projects throughout the last two difficult years. If implemented here, our equivalent should be located outside London, have lending offices spread across the UK and offer private individuals a chance to invest in its activities.

2. In 2009 KfW put about €9bn into building refurbishment. Its activities have been geared towards helping property companies and social landlords improve the poor insulation standards of post-war German housing and commercial property. It has helped improve many hundreds of thousands of homes, providing more comfortable accommodation that it is much cheaper to run. KfW’s lending has also created an effective and flexible eco-refurbishment industry. This has improved employment and skills, particularly in the less prosperous eastern parts of the country. We should copy the German emphasis on housing renovation as a primary activity of the bank, rather than let the UK entity focus on risky venture capital investments

The Guardian web pages are reverberating to the clash of arms between George Monbiot and UK supporters of feed-in tariffs for solar photovoltaic panels and other small-scale renewables. Monbiot claims solar power is an extremely expensive way of generating electricity in the UK and that the new scheme is another way of subsidising the wealthy middle class. The fans of feed-in tariffs note the success of similar schemes in other countries. They think that the cashback proposals will help create jobs in businesses that install and maintain low carbon energy sources. The UK scheme will help drive down the costs of renewable technologies and increase public support for wind and alternative sources of electricity.

The argument has focused on solar photovoltaic panels installed on domestic roofs. This note tries to quantify some of the costs and benefits of the new scheme. I’ll take one of  the simplest possible examples: an installation of 12 panels on the roof of a medium-sized house in the south west of England, where solar radiation levels are relatively high for the UK. Does solar energy make sense in this country?

George Monbiot wrote about the carbonisation of organic matter in the Guardian last month (‘Woodchips with everything. It’s the Atkins plan of the low-carbon world’, Tuesday 24 March 2009), saying it was yet another miracle cure for the climate problem. And, like previous miracle cures, he said ‘biochar’ would turn out to be a dangerous delusion. It would deflect attention from taking real action on climate change. Parts of the planet would be turned into vast forest plantations with limited biodiversity to provide feedstock for huge factories. Vital food-growing land would be lost to vast corporations farming wood for turning into biochar. It is a re-run of the biofuels disaster, he said.
