Mexico wants to produce 43 percent of its electricity from renewables by 2024, in only 6 years. It has 58 new power plants planned, the majority of them solar and the rest wind. Toward that end, in December it opened the Villanueva solar farm in the desert, with 2.3 million solar panels, generating enough juice to power 1.3 million homes. It is the largest solar project in the Western hemisphere.
