Renewable energy as one of the solutions
to the climate crisis towards a sustainable world

renewable energy access in Africa
Renewable energy still remains unused are most of the
countries as a source of energy despite it being the
solution to combat climate change. Most of the energy comes from non-renewable
sources like coal. It still remains the top choice to produce energy. Unless we
give renewable energy a serious thought, the problem of energy crisis cannot be
solved. Renewable energy sources can reduce our dependence onfossil fuelsand also helps to reduce greenhouse gas emissions (http://www.conserve-energy-future.com/causes-and-solutions-to-the-global-energy-crisis.php). The solution to the climate
crisis is a transition to 100% renewable energy for all by 2050, in a bid to
move towards a universally accessible, affordable, and zero emissions energy
system (http://www.greenpeace.org/international/Global/international/briefings/climate/COP21/The%20solution%20to%20the%20climate%20crisis.pdf).
The
increased use of renewable energies helps in mitigating climate change effects.
Climate change mitigation refers to efforts to reduce or prevent emission of greenhouse gases. Mitigation can mean using new technologies and renewable energies, making older equipment more energy efficient, or changing management practices or consumer behaviour (http://www.unep.org/climatechange/mitigation/).

A practical example of renewable energy being used is in the
United State of America whereby more than 50% of U.S. states have adopted a
renewable electricity standard—a policy that requires electricity suppliers to
gradually increase their use of renewable energy such as wind, solar,
geothermal, and bioenergy in a bid to reduce CO2 and other unhealthy air
emissions at the same time alleviating the harmful impact that fossil fuel
extraction, transport, and use have on land and water resources (http://www.ucsusa.org/clean_energy/smart-energy-solutions/increase-renewables/renewable-energy.html#.V_fLifl97IU). Renewable energy sources have potential to mitigate the
climate change crisis since no greenhouses gases are emitted, unlike in
electricity production from coal powered plants accounts which produce
approximately 25% of total U.S. global warming emissions (http://www.ucsusa.org/clean_energy/our-energy-choices/renewable-energy/public-benefits-of-renewable.html#.V_fPKfl97IV).
