The perennial argument for maintaining significant fossil fuel capacity is this: when the wind doesn't blow, and the sun doesn't shine, and the mercury drops low enough that the whole country simultaneously dials up the thermostat, then renewables on their own are not enough to keep the lights on

India's largest power utility NTPC has plans to use biomass to co-fire all its coal-based power plants. The decision is a bold move that will reduce the company's overall carbon emissions, but what challenges might it face during implementation and how will the change impact India's overall energy mix? Heidi Vella investigates

Electricity has begun to flow at Hornsea 1, a wind array that will become the world's biggest offshore wind farm off the coast of the UK. This milestone makes the UK's offshore wind sector arguably the best in the world, and with significant investment recently announced it looks set to maintain that position.

The UK Government has proposed to reduce support for anaerobic digestion projects in the UK by slashing subsidies and reducing the amount of energy they can provide. There is a lot of innovative technology in the sector, but is this enough to keep...

Researchers from a University of California-led study used detailed data sets of existing fossil-fuel burning infrastructures, such as power plants and boilers, to estimate how much carbon dioxide they would emit before they are currently expected to retire.

What does the future hold for the world's largest renewable energy source, hydropower? Hydropower is an incredibly old source of energy, tracing its usage back to the watermills that have been a staple of civilisations since ancient times. Today, it is the largest source of renewable energy in the world, with an installed capacity of over 1126GW in 2018. Hydropower is particularly prominent in China, where the world's largest power station Three Gorges power plant in Hubei province produces 22.5GW. Other massive projects also dot the country, including the Xilodu (12.3GW) and Longtan (6.3GW) dams.

An exhaustive global study has found that climate change is set to drive up energy demand significantly by 2050, suggesting policymakers and the energy industry need to take action now to prevent a surge in energy related costs over the next few decades.

A host of new technologies have been inspired by the natural world, as designers increasingly look to biomimicry when to creating new ideas for wind turbines, solar cells and hydropower. So could nature hold the answer to unlocking renewable energy?

Siemens has set a new global record for the execution of fast-track power projects by connecting 4.8GW of generation capacity to the Egyptian grid. Julian Turner asks Peter Ullrich, project director of the three combined- cycle power plants at Siemens Power & Gas Division, how it was achieved.

The decision by Iraq to invite interest in a number of solar independent power producer (IPP) projects is not the first time that Baghdad has sought to push ahead with competitively tendered IPP schemes.
