From non-renewable resources to clean and sustainable energies

The transition to a sustainable economy through renewable energy is one of the priority objectives of the United Nations, the driving force behind a project capable of meeting the energy needs of humanity.

The Energy Transition is the ‘journey’ towards a sustainable economy through renewable energy, energy efficiency and sustainable development. The ultimate goal is the abolition of coal, nuclear and other non-renewable resources, so that the mix is composed solely of renewable energy.

Renewable energy includes wind, biomass (such as biogas and sewage gas), hydropower, solar energy (thermal and photovoltaic), geothermal and ocean energy. These renewable sources should serve as an alternative to fuels such as fossil fuels (oil, coal, natural gas) and nuclear fuel (uranium).

Partial measures often have only limited potential, so timely implementation of the energy transition requires multiple approaches in parallel. Energy conservation and improved energy efficiency therefore play an important role. An example of an effective energy conservation measure is improving the insulation of buildings; a sample of energy efficiency is cogeneration of heat and electricity. Smart electricity meters can program energy consumption for times when electricity is available at low cost.

An example of a holistic approach is DESERTEC. This concept is dramatically expanding the production of electricity from adjustable solar thermal power plants in Southern Europe, North Africa and the Middle East. Linking the electricity transmission grids of these regions, in order to complement locally available renewable variable energy with surplus and adjustable renewable energy sources from other regions.

Tokelau is the first country in the world to have completed the energy transition, as it does not have an electricity mix, obtaining all the energy it needs from solar electricity.

The United Nations is promoting a revolutionary project that is now technically possible: the urgent transition from non-renewable and polluting energy resources to clean and sustainable energy. A transition capable of meeting the energy needs of humankind and which is a key component in avoiding ecological and social disasters and making a sustainable future possible.
