Solar Power Now 99% Cheaper, Reshaping Energy Security

The dream President Carter announced in 1979 is finally coming true, and it's transforming how nations protect their energy supply.

Back when Carter installed solar panels on the White House roof, the technology cost a staggering $42 per watt in today's dollars. He launched a research program hoping to make renewables affordable, with a goal of 20 percent renewable energy by 2000.

Today, solar panels cost just 26 cents per watt. That's a 99 percent price drop that has unlocked a genuine energy revolution.

Battery prices have fallen even faster, down 93 percent since 2010 alone. This combination solves the biggest challenge renewables faced: storing power when the sun sets and wind dies down.

The result is that solar plus batteries now offers the cheapest round-the-clock power in most of the world. And unlike oil or gas, once panels and batteries are installed, the fuel is free for 15 to 25 years.

Countries are taking notice. China has installed more renewable energy than the entire rest of the world combined, and over half of new cars sold there are now electric.

Europe and even parts of Africa are accelerating their transitions. Recent oil price spikes have reminded nations of a painful lesson from the 1970s: depending on oil from unstable regions creates massive economic vulnerability.

As Carter said decades ago, no one can embargo the sun or interrupt its delivery. Wind and solar exist everywhere, and they complement each other naturally since wind blows harder in northern regions and during winter months.

The technology keeps improving too. New perovskite panel designs are hitting the market with better efficiency. Factory automation continues to drive costs down.

The Ripple Effect

Every solar panel and wind turbine installed makes a country more energy independent. When oil prices spike due to conflicts or supply disruptions, nations with strong renewable infrastructure feel less pain.

China's oil demand is projected to finally decline in the 2030s as electric vehicles replace gas cars and renewable power replaces fossil fuel plants. Other Asian nations are following similar paths, racing to build energy security through homegrown clean power.

The transformation isn't complete yet. Oil consumption globally remains at record highs, and the transition needs to move faster.

But the economic case is now clear alongside the environmental one. Renewable energy offers price stability, energy independence, and protection from global supply shocks all at once.

What started as an expensive research project four decades ago has become the most practical path to energy security the world has ever seen.
