"The circular economy is an economic and industrial model that aims to keep products, their components and materials in circulation for as long as possible, while ensuring the quality of their use. This model is opposed to the linear economy, which is based on the following pattern: extraction or harvesting of resources, manufacture and assembly of goods, distribution and use, and, finally, production of waste. Solar energy, wind power, marine and hydroelectric power, biomass and biofuels are all renewable energy sources. Energy markets alone cannot achieve the desired level of renewable energies worldwide. The main principles of the renewable energy policy include diversifying the world's energy supply, promoting the development of local energy suppliesto ensure security of provision, and minimizing energy dependency"-- Provided by publisher.
