A new study published in the journal Energy Policy claims that there is a strong possibility that the world will achieve 100 percent renewable energy by 2030. Researchers and scientists came to this conclusion based on different sources of energy available and its total estimated outputs. The renewable energies considered for this study include wind power, solar power, waves and geothermal energy.
PhyOrg said that acheiving 100 percent clean energy will require building 4 million 5 megawatt wind turbines, 1.7 billion 3-kilowatt roof-mounted solar photovoltaic systems and around 90,000 300-megawatt solar power plants. The study was conducted by Mark Delucchi of the University of California, Davis along with Mark Jacobson at Stanford University.
Researchers said that the world’s energy supply will be completely dependent on renewable energy by 2030. However it may be a challenge to get rid of our dependency on fossil fuels however this reasearch finding is exciting.
PhyOrg left out a lot of other sources of renewable energy in its studies, such as the many different forms of biofuels, hydroelectric power, wave, tidal, and geothermal.
Also, the amount of energy efficient technologies for products will dramatically get better in twenty years to conserve the amount of energy we use.
I think biofuels with carbon capture are definitely going to be the future of our energy dependence, along with increasing technologies in solar and wind.
