Covid-19 Reveals Critical Flaw In European Power Systems – Lack Of Flexibility

Wood Mackenzie

Coronavirus had a sudden and dramatic negative impact on power demand, which fell by 20% in the UK during the lockdown period with similar drops across Europe. Coronavirus power demand destruction has given us a glimpse into the future when variable renewable energy (VRE: wind and solar) makes up a higher proportion of power supply. At current levels, the power system lacks the flexibility to support this variability: the bigger the share of VRE in a system, the greater the challenge.

Top 5 Developments Enabling Shift to 100 Percent Renewable Energy

Renewableenergyworld – A growing number of companies, cities, states and countries are aiming for, and achieving, a goal of obtaining power from 50 percent, 75 percent or even 100 percent renewable energy, thanks, in part, to a set of major developments that are enabling the resource shift, according to a new report from Clean Edge.

Commissioned by SolarCity, the report Getting to 100 discusses what is driving the transition to increasing levels of renewable energy consumption and identifies the successes and challenges of both governments and companies in targeting, and/or achieving, 100 percent renewable energy goals.

According to the report, these five developments are supporting the trend toward higher penetrations of renewable energy:

  • A resilient grid
  • A rise in net zero buildings and smart connected devices
  • Energy storage availability and affordability
  • Proliferation of utility-scale renewables
  • Cost-effective status of distributed solar across geographies

Distributed Solar Becomes Cost-Effective Across Geographies

The proliferation of ever-cheaper distributed solar generation – residential, commercial and community – is a key driver toward the 100 percent renewable energy goal, according to the report.

“The cost curves are undeniable,” the report said. “The plummeting prices of solar panels have been well-documented, but the industry has recently been attacking balance-of-system costs and so-called soft costs (such as marketing, customer acquisition, permitting, and installation) as well.” Tiếp tục đọc “Top 5 Developments Enabling Shift to 100 Percent Renewable Energy”
