This is far from the first 'informed' suggestion that energy will become free. Solar is becoming so cheap, and wind both cheap and plentiful, we already see periods of negative wholesale electricity prices, Christmas Day in Germany as a recent example.
Energy, or electricity at least, is beginning to further echo mobile telecoms. We already see Sonnen offering flat rate electricity and a move towards paying a monthly fee for both the electricity and the equipment.
“The promise of quasi-infinite and free energy is here,” says Thierry Lepercq, head of research, technology and innovation for Engie SA. He thinks the cost of solar power will drop below $10 a megawatt-hour ($0.01 per kWh) before 2025 in the world’s sunniest places. Engie recently conducted a “very deep modeling” of the Provence-Alpes-Cote d’Azur region of France, which has about 5 million inhabitants. The study showed those regions could run entirely on renewable energy for about 20% less than the price of electricity today.
