Changes in investment level
While clean energy investment has risen drastically over the past 20 years, its growth has not always been consistent. Investment dropped after 2008 in the wake of the financial crisis, before climbing to a new peak in 2011, then decreasing again for a few years. Significant fluctuations in the energy market as a whole played a part in wavering investments during the turbulent years following the global recession.
Unstable fossil fuel prices
In addition to environmental concerns, the volatility of oil markets in recent years have contributed to rising interest and investment in renewables. In response to swelling international oil prices during the 2008 financial crisis, investors sought to develop both renewables as well as new technologies to domestically extract fossil fuels, such as hydraulic fracturing. A surplus of shale oil and natural gas followed and led to the further destabilization of the U.S. energy market, known as the 2010s oil glut.
