Tidal power is one type of marine renewable energy, along with power harvested from waves, ocean currents, and temperature and salinity differentials from different water depths. Although tidal power is in its infancy—no commercial systems are in place in the United States—researchers at PNNL are looking at the potential benefits it offers in addition to power production. In certain areas, tidal energy may be able to partially smooth out the peaks and valleys of its own electricity production by aggregating the resources at multiple sites within relatively short distances, a trait that other renewables like wind and solar are unable to achieve. By providing steadier power to the electric grid over time, tidal energy would reduce the volatility of the system compared to other intermittent resources.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
