The Blueprint to 100% Renewable Energy

X_energy Blue Print_Trans_2019.png

A study by Energy Watch Group and LUT University have put forth a scientific model which simulates a total energy system transition form our current fossil fuel system to a 100% renewable energy system by 2050. The study, which took over four year to compile, show the total transition is not only achievable but is economically competitive to our current system and could reduce our greenhouse gas emmssions to zero even before the year 2050.

Key Points

  • A global transition to 100% renewable energy across all sectors – power, heat, transport and desalination before 2050 is feasible.

  • Solar power will make up 69% of the total energy supply by 2050, wind energy would make up 18%, with bioenergy, hydropower, and geothermal making up the rest.

  • Fossil fuels and nuclear energy would be phased out completely by 2050

  • The plan has the potential to create more than 15 million new jobs in renewable energy. Approximate 9 million jobs in the global coal industry would be reduced to nearly zero.

  • The plan would be slightly more cost effective at $59/MWh by 2050, compared to $60.5/MWh by 2015.

  • A global transition eliminates international energy dependencies and would help to solve energy-related conflicts.

Politics of the Plan

“The energy transition is not a question of technical feasibility or economic viability, but one of political will.”
– Hans-Josef Fell, President of the Energy Watch Group

The following key political support measures will accelerate the energy transition:

  • Policies and instruments focused on sector coupling and enabling direct private investment in renewable energy and other zero emission technologies.

  • Feed-in Tariff laws should be adopted to enable investments (under 40 MW) from decentralised actors, such as small and medium enterprises, cooperatives, communities, farmers and citizens. Tendering procedures for large scale investors should only be applied for utility-scale capacities above 40 MW.

  • A responsible phase-out of all state subsidies to fossil fuel and nuclear energy generation is necessary.

  • Introduction of carbon, methane and radioactivity taxes.

  • Incentives created to spur the growth of renewable energy technologies; such as tax exemptions, direct subsidies, and legal privileges.

  • Policies and frameworks that promote research, education and information sharing on renewable energy and zero emission technologies.
