A new decade of renewables

More than 260 GW of renewable energy capacity was
added to global energy supply in 2020, beating earlier
estimates and all previous records, despite the economic
slowdown that resulted from the Covid-19 pandemic.
     The International Renewable Energy Agency’s
(IRENA’s) annual Renewable Capacity Statistics 2021,
released 5 April, shows that renewable energy’s share
of all new generating capacity rose substantially for the
second year in a row. More than 80% of all new electricity
capacity added last year was renewable, with solar and
wind accounting for 91% of new renewables.
     Renewables’ rising share of the total is partly
attributable to net decommissioning of fossil-fuel power

               Windaba 2021 scheduled for October

               The South African Wind Energy Association (SAWEA) has
               opened its registration platform for WINDABA 2021, which
               will be held under the theme: ‘Renaissance of the Wind
               Energy Industry - Delivering Economic Benefits for SA’.
                   The two-day event, planned to return to the Cape Town
               International Convention Centre (CTICC) after the 2020
               hiatus, is scheduled to take place over 7 and 8 October
               2021. Now in its 10th consecutive year, the event is once
               again supported by the Global Wind Energy Council
               (GWEC).
                   Speaking to the theme, SAWEA CEO, Ntombifuthi Ntuli
               says, “We are celebrating the rebirth of the wind industry            Windaba 2021 will celebrate the rebirth of the wind energy
