BNEF: cost of new renewables rises as inflation starts to bite

Green Car Congress

The cost of new-build onshore wind has risen 7% year on year, and fixed-axis solar has jumped 14%, according to the latest analysis by research company BloombergNEF (BNEF). The global benchmark levelized cost of electricity, or LCOE, has retreated to where it was in 2019. The latter cost at $74 and $81 per MWh, respectively.

MIT study finds shift to green energy sources could mean crunch in supply of key rare earth elements

Green Car Congress

Of particular significance, one country (China) controls 98% of current supply (production). For example, in 1978 Zaire controlled 48% of the cobalt supply and yet political unrest in Zaire resulted in a disruption to global supply that became known as the “Cobalt Crisis”. Comparison of demand projections for REE (total summed).
