Answer:
Explanation:There are many avenues of "current" research, so to spark.
Improved efficiency and lower-cost photovoltaic cells,
Improved, and lower cost, battery technology,
Systems for harnessing tidal and wave power from the oceans,
Molten salt energy storage for solar reflector arrays,
Hydrogen-powered motors for vehicles,
Gas storage (hydrogen) for transportation.
Energy storage systems such as flywheels, molten salts, hydro power, etc., and
Higher efficiency motors and electromagnetic devices
Replacement of fuel-powered motors with electrical motors in transportation, including vehicles, ships, and planes.
Finding less expensive, and non-toxic materials is important. Less-enpense, and safer, alternatives to rare earth metals is sought.
