Solar farms are blooming in fields across the globe and producing a new crop: solar energy. Photovoltaic (PV) systems made up of solar panels, are fast becoming the most recognisable of renewable energy technologies.
The sudden failure of a building or bridge is mercifully a rare event, thanks largely to international or national standards: structures are designed in accordance with a design standard, using products conforming to a product standard and manufactured using techniques and to a quality level defined in a construction standard.
Geothermal energy for electric power production has a low profile yet is significant in the current and potential energy mix for a number of countries. It has also been described as the most reliable of the renewable energy sources, above weather-dependent wind, solar and hydropower.
Should we be worried about there being enough nickel to supply the transition to electric vehicles and cleaner energy sources? Given its wide range of uses in important existing and emerging technologies, this is a frequently asked question.
