There are two main types of green jobs: those that produce goods or services that improve the environment, and those that improve an existing business's environmentally unfriendly practices.

Green jobs exist in hundreds of industries, from farming to mining and telecommunications to transportation. What's more, it's possible to have a green job without sacrificing your financial goals.
