Solar energy is seen as an important step towards cleaning up human society. The process works by using radiant light and heat from the sun harnessed using a range of ever-evolving technologies like solar heating, solar photovoltaics, solar thermal energy, solar architecture and artificial photosynthesis.
The development of solar energy is so important that, in 2011, The International Energy Agency said that ‘the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries’ energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating global warming, and keep fossil fuel prices lower than otherwise. These advantages are global. Hence the additional costs of the incentives for early deployment should be considered learning investments; they must be wisely spent and need to be widely shared.’
One aspect of silver, which many people do not know about, is the amount of silver needed in order to create solar panels. Silver has long been needed in industrial applications.
Back in the days of analogue photography, film was coated with a minute layer of silver chloride, silver bromide or silver iodide. Silver has also been important for the production of motion pictures, as movie screens were once covered in paint embedded with the most reflective metal – silver – thus resulting in the ‘silver screen.’
