Over the past 150 years, we’ve changed the balance of our planet by living beyond our means. We’ve burnt huge amounts of fossil fuels (such as coal, oil, gas), bred huge amounts of methane- producing livestock and cut down vast swathes of forests, which would naturally absorb carbon dioxide from the air. If the world continues emitting greenhouse gases (GHGs) at today’s levels, average global temperatures could rise by up to five degrees Celsius by the end of this century. Energy efficiency strategy and the introduction of sustainable energy must play a leading role in helping to reduce these emissions and mitigate the effect of climate change. This demonstration will provide an overview of the opportunities and challenges associated with incorporating energy efficiency and sustainable energy production, storage and utilization and how they will impact on the economic development and social welfare of people. The workshop will include interactive sessions as the construction of solar panels to generate free energy, the assembling of an orange battery for energy storage and of a hydrogen fuel cell to illustrate the conversion of hydrogen into electricity to run an electric car.
