Do you care about issues like climate change, environmental stability, and indigenous rights? These are exactly the types of issues you'll be dealing with if you choose to become an energy economist. These economists frequently work for government agencies, research institutions, and academic organizations.
If you work for a government agency, you'll be expected to look at how the use of energy, including its production and transport, impacts the environment. You'll also calculate the cost of environmental impacts to determine which policy proposals should be undertaken to address energy needs.
Many energy economists also work for private companies and help them by advising about which energy investments to pursue. Energy economists can also use their expertise to work as energy loan specialists, energy project financial analysts, or energy business analysts. If you're hoping to get into this line of work, you'll need to get Bachelor's degree with an environmental focus.
