Global clean energy investment totaled $332.1 billion in 2018, down 8% on 2017. Last year was the fifth in a row in which investment exceeded the $300 billion mark, according to authoritative figures from research company BloombergNEF (BNEF). There were sharp contrasts between clean energy sectors in terms of the change in dollar investment last year. Wind investment rose 3% to $128.6 billion, with offshore wind having its second-highest year. Money committed to smart meter rollouts and electric vehicle company financings also increased.
However, the most striking shifts were in solar. Overall investment in that sector dropped 24% to $130.8 billion. Part of this reduction was due to sharply declining capital costs. BNEF’s global benchmark for the cost of installing a megawatt of photovoltaic capacity fell 12% in 2018 as manufacturers slashed selling prices in the face of a glut of PV modules on the world market.
Solar commitments declined 24% in dollar terms even though there was record new photovoltaic capacity added, breaking 100GW barrier for the first time.
