The history of our energy supply

Our energy comes from the sun

At any given moment, the sun sends enormous amounts of energy to Earth. About 174,000 terawatts. Humanity uses a total of about 18 terawatts; only one ten-thousandth of what is available. We literally live in abundance, but we utilize only a fraction of it.

In prehistoric times, people lived entirely on what nature provided. Wood for fire. The sun for warmth and light. Later wind to fill sails, and water to run mills. Simple, local, renewable. With few comforts - there was cold, scarcity and hard work - but in balance with what nature gave and could replenish.

Prehistoric energy use

The Industrial Revolution

With the use of coal, everything changed. Suddenly we could store and transport huge amounts of energy, and scale up industry. We built factories, built railroads and operated power plants. Oil made cars and airplanes possible. Gas provided comfortable heating in millions of homes. Fossil fuels gave us unprecedented opportunities - but also new dependencies.

Industrial revolution

What had sat underground for centuries we emitted into the air in just a few generations. Resulting in CO₂, air pollution and soil acidification. And as our economy grew, so did our dependence on a finite energy supply. We became increasingly out of balance with nature - and what it can offer us.

But the sun - it continued to shine. And slowly but surely we began to rediscover it.

The rediscovery of solar energy

First through solar water heaters, later through solar panels. What once seemed expensive and complicated became feasible for anyone with a roof. Thousands of households are now generating their own power. That's a huge step forward.

But ... the story doesn't end there.

Solar panels produce electricity when you don't necessarily need it - in the middle of the day, when you're not home. At night, when you need energy to cook, heat or watch TV, your panels produce little. Then you have to buy power from the grid - which often still runs on polluting sources. And because there is often a surplus of solar power during the day, its value drops. While in the evening the electricity pays dearly.

Home batteries make a difference

That's where home batteries make a difference. They make it possible to store self-generated electricity - from morning to night, and for much of the year even enough to meet your entire energy needs.

Just as we once learned to store grain or water for later, we can now store energy. In your own home. For when you need it.

At Suncharged, we believe the real energy transition is not just about how we generate energy, but more importantly how we use it. By storing solar energy, households become more sustainable, more independent and more future-proof.

We are closing the circle again - with technology that allows us to live off the energy nature gives us.

The sun gives. You store. It's as simple as that.
