The prospects for solar in a 1.5C world

We will need 10.7 TW of clean energy generation capacity this decade to stay on track with the most ambitious of the climate change paths agreed in Paris, which would include plenty of solar investment and jobs, according to the International Renewable Energy Agency.

Gravita Group enhances lead recycling capacity at Africa plant

The Jaipur-headquartered company carries out smelting of lead ore, lead concentrate, lead battery scrap, and aluminum scrap to produce secondary lead metal and aluminum ingots.

Camel death sparks debate over siting solar in deserts

The sharp-edged angles at a solar installation site in Rajasthan injured a camel so severely that it bled to death.    

Solar photovoltaic quality control and waste management in India 

As PV waste is set to rise rapidly in the coming decades, India needs to invest in efficient recycling technologies and devise a clear-cut policy for the safe disposal of PV waste. Guidelines for stringent quality checks and validation for both imported and locally produced solar panels are also needed to avoid early-loss solar waste.

New renewables cheaper than legacy coal or gas for almost half the world’s population

Electricity bill payers in nations as diverse as China, India, Germany, and Greece should be aware new solar projects can now generate electricity cheaper for them than legacy coal and gas-fired plants.

Hitachi ABB Power Grids to switch to 100% fossil-free electricity by year end

The company is working on electrified, reliable, and decarbonized operations and products to get closer toward a carbon-neutral future.

India could have 2.95bn tons of solar waste by 2047

Researchers led by the Indian Institute of Technology Delhi have projected the waste expected from end-of-life solar panels and related components. They assumed 347.5 GW of total installed solar generation capacity would be reached this decade. The academics said the waste would include critical metals worth around $645 trillion, 70% of which could be recovered.

IEA highlights solar’s dependence on Chinese copper processing

The sheer volume of new power lines which will be required to accommodate the rising tide of solar installations ensures copper has been included by the International Energy Agency on its list of minerals which must keep flowing if the energy transition is to stay on course. And it’s not production that’s the potential bottleneck.

Green hydrogen supply chain concerns

With South Africa holding 63,000 of the world’s estimated 69,000 metric tons of platinum reserves – according to the Statista.com website – and Russia and Zimbabwe a further 5,100 between them, the European Commission has cited the metal as an example of a potential supply chain bottleneck that could handicap its grand plans for renewables-powered hydrogen production.

Green taxonomy first step towards building a resilient society

The second wave of Covid-19 reminds us to build a resilient society. Climate Change, not unlike Covid-19, will deliver devastating effects to our planet and disrupt our way of life. So, in this climate decade, India must channel investments into sustainable activities. The first step is to construct a robust “green taxonomy” – a green list of sustainable activities.
