When it comes to energy, we’ve hit a crossroads. Fossil fuels have powered civilizations for centuries, but at a great cost to our planet. The answer lies in harnessing the Earth’s natural cycles, from the sun to the sea, to keep our lights on with a clean conscience. Not only are these renewable energy sources more sustainable, but they also promise greater energy independence and reduce our vulnerability to natural resource depletion.


Overview of Renewable Energy

Renewable energy is derived from sources that are naturally replenished on a human timescale. Unlike fossil fuels, they offer a virtually endless supply, which is music to the ears of our climate change beleaguered Earth. The sun, wind, water, and even our own waste can become powerhouses of energy, driving a revolution in how we live and work.

15. Horizontal Axis Wind Turbines

The most common type of wind turbine, with a horizontal rotor shaft and significant height to capture stronger winds aloft.

16. Micro Wind Turbines

Small-scale turbines that can generate a modest amount of energy and are relatively simple to install on a rooftop.

17. Wind Energy Storage Systems

Batteries and other storage technologies paired with wind turbines to retain and distribute power even when the wind isn’t blowing.

18. Hydropower

Using the gravitational force of falling or flowing water to generate electricity, the oldest and most common form of renewable power.

19. Hydroelectric Dams

The traditional, and still the largest-scale, application of hydropower, using large reservoirs behind dams to store water and create a dependable and constant flow for electricity generation.



20. Run-Of-The-River Hydropower

A smaller scale and more environmentally friendly version of hydroelectric dams, generating power by using the natural flow of a river.

21. Pumped-Storage Hydropower

This system uses two water reservoirs at different elevations. During peak electricity demand, water is released from the upper reservoir to the lower reservoir to generate power. During off-peak hours, the reverse occurs, pumping water back to the upper reservoir.

22. Tidal Energy

Harnessing the kinetic energy from the ebb and flow of tides, a reliable and predictable source of power.

23. Tidal Stream Systems

Similar to wind turbines, these systems are placed in the path of fast-moving tidal currents to generate electricity.

24. Tidal Barrages

Across the entrance to a bay or river, this dam-like structure uses the rise and fall of tides to generate electricity.
