Like the Japanese. But this time, you too can profit from the deluge of investments that are related to addressing global climate change by way of renewable energy technologies. Of course, a few days back I wrote about this and the fact that the investment bubble may burst (anytime soon, I hope not!). But those of you who want to put their money somewhere hot may want to consider investments in:

Uranium - touted as an emerging market, investments in uranium may potentially be big as the US government gave the go-ahead for a new generation of nuclear power plants.

Smart meter firms - if your house is to be retrofitted with smart meters, you can be sure that the companies related to smart metering jobs are going to be successful. After all, the government proposed that your house be smart metered soon.

Renewable energy stocks - my industry and sector, of course I feel that its because of the valuable contribution of RE to the global energy market and its positive contribution to climate change that makes it successful. Churning out cash, well, that's a side thing hehe.

Carbon credit firms - my friend is in carbon credit and yes, they are racking up business. Europe has tremendous demand and this is good for new and existing businesses.

Ethanol companies - I manage ethanol plant development and yes, despite all the setbacks, ethanol will become huge.

Energy funds - for the purist, go for an energy fund. High risk, yes. But worth it!
