Storing CO2 underground can curb carbon emissions, but is it safe?

At first glance, it almost sounds crazy. Can we really take carbon dioxide emissions from an industrial plant and store them underground? To find out, research is currently taking place to test if such an idea is not only viable but safe, and prove that to the public. By Jonathan O’Callaghan This approach is known as carbon capture and storage (CCS) and it’s been around for decades but has never really taken off. In its recent reports, however, the UN Intergovernmental Panel on Climate Change (IPCC) said that CCS could have a key role to play if we’re going to meet our climate

India soon to have guidelines to save birds from wind energy farms

Alarmed by the threats from wind energy farms to birds, including migratory birds and raptors, a panel of forest experts of India’s environment ministry has now suggested a series of measures to be adopted by all the wind power companies in India for ensuring the protection of birds. For instance, it has suggested painting the vane tips of wind turbines orange, to prevent birds from flying into the turbines. The requirement for such measures has increased as the world is moving away from fossil fuel and towards renewable energy, mainly wind and solar power, to avoid the worst effects of climate change.

Light pollution lures night-time pollinators away from plants

Populations of bees, bats, butterflies and other pollinators have been declining for decades due to habitat loss, disease, pesticides and climate change. Now, scientists have documented yet another threat to pollinators: night-time light pollution.

In a recent study in Nature, ecologists showed that plants growing near streetlights were pollinated far less often at night and produced fewer fruits than their unilluminated counterparts. In turn, this may compromise the efficiency of daytime pollinators in the same fields, the authors conclude.

Geothermal energy could light up rural Ladakh

Geothermal energy is not new to India. As early as 1973, the Indian government submitted a report on geothermal hotspots of the country. This happened after the Geological Survey of India (GSI) performed shallow drilling exploration, which showed the potential hot springs and geothermal locations. It is estimated that India has the potential to generate 10 GW of geothermal power.

India becoming biggest emitter of sulphur dioxide

While the world has been preoccupied with reducing carbon dioxide in the atmosphere, which is generated by burning fossil fuels, sulphur dioxide (SO₂) emissions have not received the same attention. Produced by burning coal, wood, petrol, diesel or farm stubble, SO₂ forms a large part of the pollution haze enveloping cities in northern India every winter. Most of the SO₂ in Indian skies is emitted when power plants burn coal to produce electricity. Typically, coal contains 3% of sulphur, but coal from Assam in India is known to have higher content.

The Uncertain Death Of King Coal

After three years of declining coal production, China has suddenly seen a rise in both its production and consumption. While analysts debate whether this is a mere blip in an overall declining trend of coal use, the rest of Asia is also caught in the midst of a strange debate where the death of coal is being celebrated while, at the same time, official consensus seems to be that coal will continue to be a large part of future plans.
