Toilet paper is the only thing Americans should flush down toilets, the Environmental Protection Agency says, adding that disinfectant wipes and other products clog sewer systems and threaten the country's wastewater infrastructure. The EPA says "fully operational wastewater services" are needed to combat the coronavirus and protect public health.
The Waukesha Water Utility in Wisconsin plans to open a bidding round soon for six contracts, each ranging from $40 million to $60 million, that will support a new drinking water system the city is mandated to have up and running by September 2023. Upon completion, Waukesha will buy drinking water sourced from Lake Michigan from Milwaukee and eliminate the use of underground wells that contain elevated radium levels.
In a new study published in the journal Global Change Biology, a team of researchers from 20 countries highlight a gap in scientific knowledge about how stormwater might affect phytoplankton growth and the health of lakes and similar freshwater bodies. Because climatologists expect climate change to cause more intense and frequent storm events, the global research community needs to devote resources toward predicting the response of phytoplankton as these conditions change, study authors argue.
Rising waters and strengthening storms could greatly compromise San Diego's water infrastructure while destroying 90% of its beaches and most of its businesses over the next 80 years, according to a city assessment. The report does not specify a cost estimate for inaction and does not estimate property and infrastructure damage or the cost of service disruption or insurance liability.
Renewables are still cost-effective and remain attractive investments for companies pursuing clean energy goals, despite the uncertainty created by the coronavirus, writes Sarah Golden of VERGE Energy. Profitable tech companies such as Google and Microsoft may see minimal disruption and, while the pandemic may complicate renewables financing and cause project delays, those companies will likely continue to embrace their clean energy agendas, she writes.
The US continues to lead the world in corporate power purchase agreements, with American wind and other renewable energy projects accounting for about 16 gigawatts of the 20 GW worth of deals signed worldwide in 2019, says RE-Source. The European Union only saw 2.5 GW worth of renewable energy PPAs last year, partially because the European market is less mature and carries greater risk, it says.
Tax credits and grants effectively drive renewables, and can help address climate change while helping the US economy recover from the coronavirus, writes Ed Crooks of Wood Mackenzie.
Siemens Gamesa Renewable Energy has agreed to supply Eurowind Energy with eight SG 5.8-megawatt 170 machines for the 46-MW Knostad site in Sweden. The deal includes a 25-year service agreement.
Triconti ECC has reportedly secured approval from the Philippines government to advance a pair of offshore wind farms with a combined capacity of 1.2 gigawatts, although timelines and project details have yet to be released. Triconti ECC is an international consortium featuring companies from the Philippines, Switzerland and Germany.
Enercon has erected a prototype of its 4.2-megawatt E-138 EP3 E2 machine in Germany and will begin testing the model. The unit is expected to produce about 10% more output per year than Enercon's 3.5-MW E-138 EP3 E1 machine.
