World’s largest floating solar park to be built in Singapore

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.

The output of solar plants can be increased by 5–15% by installing them on water rather than land.

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.

According to the results
of the research, the solar power plant would have a minimal impact on the environment and water quality, so extension of the floating solar plant
has continued, and it is planned that the park, initially of 1 MWp capacity, will be upgraded to 50 MWp.

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.

The worst ocean polluting countries to join the effort to eliminate waste

The ten members of the Association of Southeast Asian Nations (ASEAN) are set to adopt a joint declaration to combat marine plastic waste.

DiCaprio sends the message again: we are still on track to destroy our world

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.

Costa Rica sets an example

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.

Global temperature may rise by as much as 3 degrees

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.

Extensive cooperation to stop marine pollution

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.

German cities declare climate emergency

During environmental and climate emergencies, local decision-makers must place an even greater emphasis on the principle of ecological sustainability in their decisions.

Plastic Pirates remove one tonne of plastic daily from Lake Tisza in Hungary

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.
