The cost of keeping a golf course looking good has traditionally required massive amounts of water, fertilizers, and toxic pesticides that have been doing great damage to the environment. But as sustainable practices become more popular across the globe, many golf facilities go green.
The Hawaiian Legislature passed a bill this week setting a goal for the state of reaching 100% renewable power by 2045. If approved by Governor David Ige, Hawaii will be the first state to officially aim for generating all of its electricity from renewable resources. New York and California have had longer standing initiatives to reduce emissions by 2050 below 80% of the levels from 1990, but no bill to date is as ambitious as Hawaii’s.
A collaboration between researchers at the University of West England Bristol (UWE Bristol) and Oxfam, an international organization dedicated to fighting poverty, is proving that urine might be an invaluable source of electricity in refugee camps and other impoverished areas. For decades, utilities in developed countries have derived energy from the methane found wastewater, but in areas where such complex treatment schemes are not possible, simple solutions such as a “pee-power” toilet could offer an inexpensive and desperately needed source of energy.
An international team of researchers led by engineers from the University of Toronto analyzed resource consumption data from the world’s twenty-seven largest cities. The survey, published this week, analyzed cities’ natural gas and electricity use, and waste disposal. Findings could be used to create strategies for making the worst offenders more sustainable.
