CLEAN ENERGY REVOLUTION
The Path to Luma illustrates what's possible in the clean energy future. The technologies SAM uses in the game are modeled after real-world energy devices that are safe, reliable, affordable, and sustainable.
We need to move quickly and with purpose to bring about a clean energy revolution. While the energy problem may seem complex, the need for action is clear.
Most of Earth's energy comes from a fusion reactor some 93 million miles away — the sun! In fact, more solar energy reaches our planet in one hour than humankind consumes in a year. Solar panels capture this abundant energy and convert it to clean electricity or heat. And with continual technological innovations, solar has become one of the cheapest renewable energy options in the world.
Solar energy also directs the movement of warm and cool air across our planet — better known as wind. The spinning blades of a wind turbine convert the wind’s kinetic energy into mechanical power that generates electricity. No matter which way it blows, humans have been putting wind to work for centuries. Today, we can turn it into clean power as efficiently as ever.
Like a squirrel storing nuts for the winter, a battery stores extra energy for when supply is low. Batteries capture excess energy produced by solar and wind and save that power as chemical energy for later, when the sun has set or the winds are quiet. Our batteries get more and more efficient every day – which brings us closer to a time when we can store all the clean power we want for whenever we want to use it.
Water & Energy
Water-powered electricity generation comes in a number of forms, from capturing the kinetic energy of rivers and oceans to extracting the hydrogen from H2O to use as fuel. Additionally, excess power generated by renewables can be used to desalinate and purify water in areas with a fresh water shortage. However we use our water resources, respecting the surrounding ecosystem is crucial.
Waste-to-energy technologies make the best of a smelly situation by repurposing all the waste we’ve cast aside as useful energy resources, minimizing the environmental impact of our trash. When battery storage isn’t enough to balance the ebb and flow of renewables like solar and wind, waste-to-energy technologies can generate electricity on demand.
It’ll take time and ingenuity to power our world without energy sources that produce greenhouse gas emissions. What can we do to improve our fossil fuel energy sources? New technologies can help reduce our carbon footprint by capturing emissions that would otherwise end up in the atmosphere and storing them or repurposing them.
