Solar power converts sunlight into electricity or heat, making it one of the most widely used renewable energy sources.

Photovoltaic Solar Panels
convert sunlight directly into electricity using semiconductor materials such as silicon.

Concentrated Solar Power
generates heat to drive steam turbines for electricity production, using mirrors or lenses to focus sunlight.

Floating Solar (Floatovoltaics)
consist of solar panels installed on bodies of water. They reduce land use and improve efficiency by keeping panels cool.

Building-Integrated Photovoltaics
incorporates solar technology into traditional building materials such as windows, façades, or rooftops.

  • Solar is scalable from small to large systems.
  • It has become one of the least expensive sources of electricity.
  • Battery storage makes solar power available 24/7.

Wind turbines harness the power of wind produced from mechanical energy to ultimately generate electricity.

Onshore Wind
are turbines installed on land and are the most cost-effective form of wind energy.

Offshore Wind
are turbines placed in the ocean, where winds are stronger and more consistent, lead to higher energy output.

Floating Offshore Wind
are turbines that are mounted on floating platforms which allow for deep-water deployment.

Vertical-Axis Wind Turbines
can capture wind from any direction and unlike traditional horizontal axis turbines, these work well in urban environments.

  • Offshore wind farms have the potential to power entire cities.
  • Floating wind technology expands the potential for wind capture.

Electrolyzers use electricity to split water into hydrogen and oxygen through electrolysis. When powered by renewable sources like solar or wind, they produce green hydrogen, a carbon-free fuel vital for the clean energy transition.

Solid Oxide Electrolyzers
operate at high temperatures and can utilize waste heat from industrial processes.

Proton Exchange Membrane Electrolyzers
use a solid polymer membrane for efficiency and a rapid response time.

Alkaline Electrolyzers
operate with a liquid electrolyte solution.

  • Green hydrogen from electrolyzers can be stored and used as an energy carrier, industrial fuel, or to power fuel cells in transport.
  • They decarbonize hard‑to‑electrify sectors like steel, chemicals, and heavy transportation.
  • Electrolyzer demand is on the rise as countries invest in hydrogen to meet climate goals.

Batteries store excess electricity from renewable sources, providing that power when needed.

Lithium-Ion Batteries
are highly efficient and energy dense and can be found in consumer electronics, EVs, and more.

Solid-State Batteries
are the next generation of lithium-ion, with improved safety, energy density, and lifespan.

Flow Batteries
use liquid electrolytes stored in external tanks, making them ideal for long-duration grid storage.

Sodium-Ion Batteries
use more abundant and less expensive materials and serve as a promising alternative to lithium-ion.

Gravity-Based Storage
use gravitational potential energy to store and release electricity.

  • Batteries reduce reliance on fossil fuels and provide 24/7 energy storage.
  • Grid-scale battery storage helps manage energy storage demands by stabilizing electricity supply.
  • Advances in battery chemistry and recycling make storage more affordable and sustainable.

Heat pumps transfer heat instead of generating it, making them one of the most energy-efficient ways to heat and cool buildings.

Air-Source Heat Pumps
extract heat from the outdoor air and move it inside (or vice versa for cooling).

Water-Source Heat Pumps
transfer heat to and from a nearby body of water.

District Heating and Cooling Heat Pumps
are large-scale systems that serve multiple buildings from a central heat pump, maximizing efficiency in the area.

Hybrid Heat Pumps
combine a heat pump with another heating source (like a gas furnace) for better performance in extreme temperatures.

Ground-Source Heat Pumps
transfer heat by circulating fluid through underground pipes, absorbing warmth from the earth in winter and releasing excess heat into the ground in summer.

  • Heat pumps are 2-5 times more efficient than conventional heating and cooling systems.
  • They significantly reduce reliance on fossil fuels for home heating.
  • Many governments incentivize heat pump adoption as a key renewable solution.
