Al writes: "The economy has hit green energy technologies hard, but technologies focused on energy efficiency and clean coal are still attracting money. Over the next few years, venture capitalists say that the biggest winners in clean tech will most likely be companies with technologies that improve efficiency. Such ventures often take advantage of cheap sensors, communications hardware, and software packages to monitor and control energy use both in buildings and on the electricity grid. High-capital businesses are now more likely to succeed if they can attract foreign funding. For instance, Great Point Energy, based in Cambridge, which has developed a process for converting coal into natural gas, has attracted $100m in funding from China."
