With a previous 50-50 split between equity and debt investment funding for the off-grid market lurching to 84% borrowing, and commentators stating most of this year’s backing was agreed before the onset of Covid-19, fears are mounting about the prospects for the sector.

Researchers in the UK have analyzed 25 years of electricity-production and carbon emissions data from 123 countries. Their findings show renewables are considerably more effective than nuclear in reducing carbon emissions from energy generation and that the two technologies tend to get in each other’s way when considered in a joint approach.

Clean energy is critical to solving our climate crisis. But we need to consider the full environmental and human health impacts of solar energy generation across its entire lifecycle, including mining, manufacturing, use, decommissioning and recycling. This requires us to identify critical stages in the production process, and how choices in materials and chemicals at different stages of production influence each other.

The iron and steel sector is the ‘world’s largest industrial source of climate pollution.’ This steel mill in Pueblo, Colorado, will be the first in North America to rely on solar power.

As the bloc pushes its digital and green transition agenda, policymakers have looked at the raw materials required. Little is mined, processed or assembled in Europe at present but the European Commission has a plan…

With the SolarPower Summit 2020 taking place this week, organizer SolarPower Europe has assessed the plans drawn up by member states would mean the bloc sourcing 33.1-33.7% of its energy from clean power by the end of the decade, with the help of 19 GW of new solar per year.

Rising volumes of solar capacity are to be welcomed but, as panelists at a session of today’s SolarPower Europe event discussed, the technology must be kept ethical and responsible. That means industry working together; new, harmonized, mandatory and voluntary policy instruments; and a focus on quantifiable, life cycle-based investor criteria.

Dozens of solar companies are claiming renewable energy certificates issued for “wood-burning” biomass technology are unconstitutional as most such facilities are fueled by wood pellets co-fired with coal in older power plants. A constitutional court decision is expected within two years.

Built in Gangba County, in Xigaze, Tibet, the 40 MW/193 MWh facility was deployed at more than 4,700m above sea level and is functioning as a demonstration project for the ancillary services the technology could offer the Tibetan grid.

The Palestine Investment Fund wants to install solar systems with an average generation capacity of 70 kW on 400 public schools.
