Addressing environmental issues is a big topic. There are many different ways to approach these issues, some based on individual actions and others on collective actions, some passive, some active. the greentomato way is to live our lives and build businesses according to a set of values that we think are pragmatic and can make a real difference. But we are always keen to hear new ideas, to challenge our assumptions and to improve and accelerate our progress. We think improving the world should be an inclusive, democratic process underpinned by transparency and debate. We believe any genuine attempt to improve the world we live in should be listened to and discussed. We provide a platform for these debates through an open blog.  Let us know what you think on our blog page.

Manufacturing a solar panel consumes more energy than it will ever deliver.

Truth: Electricity generation plants are measured by the energy yield ratio which is the energy delivered by a system over its lifetime, compared to the energy required to make it. In northern Europe a grid-connected system, with a lifetime of 20 years, produces 4 times the energy required to make (it has an energy yield ratio of 4). In sunnier climes this figure goes up to 7.
