Bill Gates presented this month an interesting lecture on energy and environment at TED2010. About the lecture, from TED: "At TED2010, Bill Gates unveils his vision for the world's energy future, describing the need for "miracles" to avoid planetary catastrophe and explaining why he's backing a dramatically different type of nuclear reactor. The necessary goal? Zero carbon emissions globally by 2050."
After Gates left his day-to-day role with Microsoft, he focused on philanthropy through his foundation. He has a website entitled The Gates Notes, where he publishes his thoughts, ideas and notes. Recently, he started to use Twitter to share his ideas.
Bill Gates published a post with some comments on his lecture: "It’s the first time I’ve spoken in public on the topic, but I’ve been studying energy and climate change over the last couple of years, and have been lucky to meet fairly regularly with some of the leading scientists in the field."
"In the presentation, I talked about the massive innovation effort needed to deliver “energy miracles,” breakthroughs that will make zero-carbon energy generation possible. There are many promising approaches which we need to continue pursuing aggressively: CCS, Nuclear, Wind, Solar PV and Solar Thermal – but they all have challenges that must be addressed. And the only way to get there is through innovation."
