Larsen & Toubro's (L&T) plans to invest $12 billion in green energy over the next five years. The investment will be used to develop solar, wind, and hydropower projects in India and overseas. L&T is one of India's largest engineering and construction companies. The company has a long history of working in the energy sector, and it is well-positioned to take advantage of the growing demand for green energy.
Climate change is a complex issue with far-reaching consequences. One of the potential impacts of climate change is an increase in the frequency and severity of earthquakes and volcanic eruptions.
Researchers from the City University of Hong Kong (CityU), in collaboration with other institutions, have developed a highly efficient artificial photocatalytic system that surpasses natural photosynthesis in converting carbon dioxide into methane, a valuable fuel, using light. This innovative system offers promising potential for contributing to the goal of carbon neutrality.
An international drilling expedition led by researchers from the GEOMAR Helmholtz Centre for Ocean Research in Kiel and the University of Oslo has provided compelling evidence that hydrothermal vents were a key driver of global warming about 55 million years ago. Published in the journal Nature Geoscience, the study reveals that these vents were active in very shallow water depths or even above sea level, allowing significantly larger quantities of methane to enter the atmosphere than previously believed.
Archaeologists from the University of Exeter have harnessed laser scans from the Environment Agency's National LiDAR Programme to uncover a previously unknown Roman road network that spanned across Devon and Cornwall. This remarkable discovery challenges existing assumptions about the Roman road system and offers insights into the historical connections between significant settlements and military forts.
A groundbreaking study by researchers from the University of Bristol has uncovered that Heliconius butterflies possess spatial learning capabilities, marking the first experimental evidence of such skills in any butterfly or moth species. Published in Current Biology, the findings indicate that these butterflies can remember the locations of food sources across substantial distances, challenging previous assumptions about insect cognition.
A recent study led by researchers at Washington University in St. Louis highlights that the impact of wildfires on climate change may be more substantial than previously understood. The study, published in Nature Geoscience, delves into the role of "dark brown carbon," a previously unidentified class of particles emitted as part of wildfire smoke. The findings suggest that these particles contribute significantly to the warming effect, necessitating revisions in climate models and strategies to address a changing environment.
Amidst relentless heatwaves, scientists predict that July is on track to become the hottest month ever recorded, surpassing previous records set in 2019. With several days left in the month, experts are confident that this year's record will be shattered. The sweltering temperatures are attributed primarily to the relentless consumption of fossil fuels, according to climate researchers. UN Secretary-General Antonio Guterres warns that the world is entering an "era of global boiling," and US President Joe Biden labels climate change an "existential threat."
Delhi's draft climate action plan aims to reduce the city's reliance on hydropower from other states. The plan cites climate change as a major factor in this decision, as changes in temperature and precipitation patterns could make it more difficult to generate hydropower in the future.
Shifting away from fossil fuels is leading to a transformation in home heating systems, as the UK aims to eliminate gas boilers by 2035 to reduce carbon emissions. The main contender for replacing gas boilers is the heat pump due to its high efficiency, converting one unit of energy into about three units of heat. However, the transition is not straightforward. Heat pumps operate at lower water temperatures, necessitating larger radiators and better insulation, which can increase costs. While heat pumps are more energy-efficient, electricity costs about three times more than gas, partly negating the efficiency gains.
