Electrifying the global energy system with clean energy is the only way to reach the targets set by the Paris agreement on climate change and avoid the catastrophic scenarios outlined by the recent IPCC report. In an interview with pv magazine, Christian Breyer – Professor of Solar Economy at Finland’s Lappeenranta University of Technology – explains a 100% renewables model is not only technically feasible, but also the cheapest and safest option. With solar and storage at its core, the future energy system envisaged by Breyer and his team will not only stop coal, but also nuclear and fossil gas, while seeing solar reach a share of around 70% of power consumption by 2050. By that time, PV technology could cost a third of its current price.
The farming sector alone offers a potential $40bn marketplace, thanks to rice transplanting, pesticide spraying and grain harvesting – says the Council on Energy, Environment and Water thinktank.
The nation installed 4.9 GW of solar, surpassing the USA – which installed 4.7 GW – to become the second largest solar market in the first half of the year, second only to China’s 24.3 GW.
According to a UC Berkeley study, the falling costs of storage technologies will make it possible for Sub-Saharan countries to rely on decentralized systems based mainly on solar-plus-storage, bringing access to electricity to more than 600 million people.
Recent analysis from the Department of Energy shows the Midwest and Plains States lead, but the coasts are on track to catch up thanks to mandates.
The government wants to help the provinces of eastern Indonesia – in particular Papua, which has the lowest electrification rate in the country. Policymakers are in talks with the Asian Development Bank and seeking advice for implementation.
Looking at a scenario, in which the Spanish residential solar market is booming again, energy consultancy, ecoSynergies finds that the energy system could save billions, both in terms of CO2, and fuel and grid costs. Additionally, introducing the EU’s suggestion to fairly compensate prosumers for their surplus energy, would allow households to slash payback times for their solar systems by more than a half. In some cases, the amortization period could go down from 25 to seven years.
The Accelerating Battery Storage for Development program is intended to leverage US$4 billion in new investments, and to support projects for utility-scale solar parks with battery storage, off-grid systems, including mini-grids, and stand-alone batteries.
