With fuel prices rising, a focus on energy independence in the European Union, and the rise of startups working on technologies that can create a future of sustainable energy, it’s clear that the world’s energy market can no longer rely on the resources of the past. While technologies that use solar, wind, and geothermal energy have been around for decades, many countries are hesitant to make them a primary power source. The science behind sustainable sources of energy is solid and innovations in this sphere will soon create eco-friendly and cost-effective energy solutions for our growing global energy market. In the US, specifically in Texas, consumers are provided with information and tools through websites like choose energy texas which allows them to find and compare energy rates, as well as choose which energy plans would best work for them.

One of the primary sources of renewable energy is the sun. Modern solar energy technologies were first invented in the 1950s with the first photovoltaic cell, but humans have understood the power of sunlight since ancient history. Primitive forms of passive solar energy use were present in ancient Egypt, Rome, and Native American civilizations. The ancient Egyptians carefully built homes and temples to take in sunlight throughout the daytime, which, through insulation, kept their homes warm during the cool nighttime.

In ancient Rome, bathhouses traditionally burned wood to keep the water warm. Still, as wood became scarce, large windows could insulate the bathhouses and keep water temperatures hot even without a fire. There are still many new developments in solar energy technology. Solar panels may soon be easily integrated directly into a home or building’s windows.

Wind energy, too, is nothing new – the sailboat probably being the most notable example of using the wind to power a device. But even the windmill was present in some ancient civilizations, with archeological evidence of large turbines powered by high winds being used to ground floor in eastern Persia for thousands of years. Current wind technology seems to have stayed largely the same, but many startups worldwide are innovating new models of higher-efficiency and cost-effective windmills.

Unique methods of energy storage have also been around for many centuries. As previously mentioned, the most common energy storage method was simply effective insulation techniques, which many societies used to heat and cool their homes and buildings without access to modern air conditioning and heating systems.

A unique form of energy storage takes a different approach. The flywheel, present in many inventions – from the ancient potters’ wheel to the centuries-old steam locomotive – stores energy from a primary source as kinetic energy. Amber Kinetics, the leader in flywheel energy storage solutions, has elevated this technology to ensure an efficient, sustainable, and safe design.

With traditional power sources proving to be unreliable and unsustainable, it’s time to turn the clock back and look at past energy sources and storage techniques.
