Solar accounted for 38% of all net power capacity installed globally last year, ranking first among all renewables, according to the report by UN Environment, the Frankfurt School-UNEP Collaborating Centre, and Bloomberg New Energy Finance (BNEF). Total renewables, excluding large hydro, were responsible for a record 61% of the net power capacity additions in 2017, while the share of fossil fuel power plants was just 27%.
Investments in renewable power capacity reached USD 265 billion (EUR 216bn). In addition, USD 45 billion were invested in large hydro projects. Fossil fuel power generation investments amounted to USD 103 billion, while nuclear power plant investments stood at USD 42 billion.
China accounted for USD 126.6 billion of the total renewables investment and was the top solar market last year.

In addition to that, a record 1.2 GW of behind-the-meter and utility-scale battery storage systems were installed last year, and roughly 3.3 GW of utility-scale projects were announced.
The power generated by wind, solar, biomass and waste-to-energy, geothermal, marine and small hydropower plant reached a share of 12.1% in 2017, up from 11% in 2016, avoiding around 1.8 gigatonnes of carbon dioxide (CO2) emissions.
