Investment trends in 2016 Energy investment by sector Total energy investment worldwide in 2016 was just over $1.7 trillion, accounting for 2.2% of global GDP. Investment was down by 12% compared to IEA’s revised 2015 energy investment estimate of $1.9 trillion. Spending in energy efficiency rose by 9% while spending in electricity networks rose by 6%, yet these increases were more than offset by a continuing drop in investment in upstream oil and gas, which fell by over a quarter, and power generation, down 5%. Falling unit capital costs, especially in upstream oil and gas, and solar photovoltaics (PV), was a key reason for lower investment, though reduced drilling and less fossil fuel-based power capacity also contributed.
