Renewable Energy for Homes and Businesses

Detailed overview of innovation with sample startups and prominent university research

What it is

Renewable energy for homes and businesses encompasses the adoption of clean energy sources like solar, wind, geothermal, and biomass to generate electricity and heat directly on-site. This shift away from fossil fuels empowers individuals and businesses to reduce their carbon footprint, enhance energy independence, and contribute to a more sustainable energy future.

Impact on climate action

Renewable Energy for Homes & Businesses accelerates climate action by promoting a low carbon lifestyle. It reduces dependence on fossil fuels, lowers carbon emissions, and fosters sustainable energy consumption patterns, thus contributing significantly to global efforts in mitigating climate change and advancing towards a greener future.

Underlying
Technology

Solar Photovoltaic (PV) Systems: Solar panels convert sunlight directly into electricity using photovoltaic cells. Rooftop solar installations are becoming increasingly common for homes and businesses, providing clean energy and potentially reducing electricity bills.
Wind Turbines: Wind turbines harness the kinetic energy of wind to generate electricity. While large-scale wind farms are prevalent, smaller wind turbines can also be installed for residential and commercial use, particularly in areas with consistent wind resources.
Geothermal Heat Pumps: Geothermal heat pumps utilize the relatively constant temperature of the earth to provide efficient heating and cooling for buildings. They transfer heat from the ground (or water source) into the building during winter and reverse the process in summer, minimizing energy consumption for climate control.
Biomass Energy Systems: Biomass energy systems utilize organic matter, such as wood pellets or agricultural residues, to generate heat or electricity through combustion or gasification. These systems can be used for residential and commercial heating or combined heat and power (CHP) applications.
Energy Storage Systems: Integrating energy storage systems, such as batteries or thermal storage, with renewable energy installations allows homeowners and businesses to store excess energy generated during peak production periods and use it during times of low production or high demand.

TRL : 8-9 (Solar PV and wind energy are closer to TRL 9, while geothermal and biomass systems are around TRL 8)

Prominent Innovation themes

Building-Integrated Photovoltaics (BIPV): BIPV systems integrate solar panels directly into the building’s structure, such as the roof, façade, or windows, providing both clean energy and aesthetic appeal.
Floating Solar Farms: Floating solar farms are gaining traction, utilizing water bodies for solar panel deployment, especially in areas with limited land availability.
Smart Microgrids: Smart microgrids integrate renewable energy sources, energy storage, and intelligent controls to manage energy distribution and enhance resilience in local energy systems.
Virtual Power Plants (VPPs): VPPs aggregate distributed energy resources, such as rooftop solar installations and electric vehicle charging stations, to create a network of interconnected energy assets that can be controlled and dispatched like a traditional power plant.
Community Solar: Community solar projects allow multiple individuals or businesses to share the benefits of a single solar installation, providing access to clean energy for those who may not have suitable rooftops or the financial resources for individual installations.
