  Global energy demand is constantly increasing, so the energy sources we use, and the efficiency of energy use are of paramount importance for the future of humanity. Methanol can play a key role in the sustainable use of natural resources, in the efficient and smooth transition from a fossil oil-based energy system as well as in reducing greenhouse gas emissions. Long-term thinking will result in an increase in the use of renewable energy sources, which will favour the spread of green methanol technology and thus the use of a carbon-neutral fuel. The raw materials for the production of green methanol may include municipal solid waste, agricultural waste, renewable hydrogen and carbon dioxide and the methanol has many uses, both as fuel and chemical feedstock. It also provides an opportunity to chemically store excess renewable energy from intermittent sources, thereby reducing dependence on fossil fuels. The price of electricity used for electrolysis is the main determinant of the economical production of green methanol, so the reduction of the cost of solar and wind energy greatly contributes to the competitiveness of carbon-based production.
