Solar farms installed in agricultural areas and solar panels fitted to the roofs of buildings are no longer a rarity these days. Their efficiency, however, is not optimal, and occupying crop land isn’t a very practical solution, either. In China and Singapore, attempts are being made to maximize the production of renewable energy by using waterborne, floating photovoltaic power generation systems.
In recent years, floating solar parks on water reservoirs to supply energy have become increasingly common. In contrast with roof-mounted solar panels, there is nothing to cast a shadow to limit exposure to the sun, while the reflexivity and cooling effect of the water increases the efficiency of the solar panels.
Mr Masagos Zulkifli, the country’s minister for the environment and water resources has recently announced that by 2021, they will build the world’s largest floating solar park. Experimental projects were began at Tengeh Reservoir in 2016, followed by engineering and environmental protection studies in 2017.
The installation of additional 50 MWp systems is planned in the future, while at Kranji Reservoir, a 100 MWp system could be built, which would produce the annual energy requirement of
27,000 four-person families, resulting in a 52 kilotonne reduction in carbon dioxide emissions, equivalent to the removal of 11,200 cars from the roads each year.
Researchers at the University of Szeged are working on a nanotechnological water treatment device. Their innovation may provide clean water for millions worldwide in the future.
Leonardo DiCaprio, the Hollywood star famous for his environmental activism, has joined billionaire investors and philanthropists Laurene Powell Jobs and Brian Sheth to found a new non-profit world organisation for environmental protection.
Speaking in Abu Dhabi, UN Secretary General António Guterres emphasised that the process of climate change is happening faster than predicted.
The ten members of the Association of Southeast Asian Nations (ASEAN) are set to adopt a joint declaration to combat marine plastic waste.
Only a few years after the brutally honest documentary Before the Flood, a new film has been made, featuring Leonardo DiCaprio, about the shocking consequences of global warming. Ice on Fire seeks to find out whether we can still reverse the impact of climate change.
The Central American country has been a paragon of environment-friendly governance for decades. It has set the ambitious goal of phasing out fossil fuels altogether by 2050.
Due to the insufficient commitments of governments so far, global temperature may increase by twice the tolerable amount, 3 degrees Celsius, by the end of the century relative to the preindustrial period, warned UN Climate Change Executive Secretary Patricia Espinosa.
At their meeting in Japan, the environment ministers of G20 countries agreed on a global framework for the introduction and application of measures to tackle the issue of marine plastic waste pollution.
During environmental and climate emergencies, local decision-makers must place an even greater emphasis on the principle of ecological sustainability in their decisions.
Competitors in the 1st Tisza Lake Plastic Cup collected almost three tonnes of waste over the three-day event. As the organisers and the participants emphasised, that is only the tip of the iceberg, as the floods of recent weeks have spread much more waste around the flood plain of the river.
