A new study shows the number of clean energy jobs in Indiana increased 4.7 percent in 2018, however that growth could stall moving forward. An analysis of energy jobs data from Illinois-based Clean Energy Trust and nonpartisan business group Environmental Entrepreneurs, or E2, says the state’s sector added more than 3,800 jobs last year, bringing the total number of clean energy jobs to nearly 87,000. Micaela Preskill, Midwest advocate for E2, says the growth was led by an 18 percent increase in advanced transportation-related jobs.
