Ask HN: How can I direct my experience towards renewable energy?

I'm a computer engineer with 15 years experience on a variety of platforms, architectures, programming languages and so on.

I'm currently looking for a bit more. Although it's a huge field, I feel like I've done my time learning and doing things around 'computers'. I see a big future in renewable energy, not just as a new industry, but because I'm as passionate about it as I was 15 years ago when I discovered programming.

I'd be interested to see any thoughts or ideas from people involved in or passionate about the field.
