Decentralized Energy Systems Driving Sustainable Change
The shift towards decentralized energy production is revolutionizing how we manage our energy needs, directly addressing the mega challenges of reducing our reliance on fossil fuels and optimizing our energy consumption. With renewable energies such as wind, solar and even indoor light, we can create energy locally.
In recent decades, the transition to renewable energy has decreased the use of fossil fuels. However, the typical setup of wind and solar farms are located far from consumption sites, resulting in inefficiencies and power losses during transmission.
Advantages of Decentralized Energy Systems
Decentralized energy systems help overcome these inefficiencies by enabling energy generation closer to where it is used. Small-scale technologies, such as residential solar panels and local wind turbines, empower homes and businesses while also contributing to global efforts to reduce carbon emissions. Notably, the building sector, responsible for nearly 40% of global CO2 emissions, benefits immensely from this approach as buildings themselves can both generate and use clean energy, reducing their carbon footprint significantly.
To further address the mega challenges, the building sector must also optimize its energy consumption. An increasing number of IoT sensors are being implemented for this purpose, that all require power. One significant challenge with retrofitting these sensors into existing buildings is the unsustainable maintenance surrounding battery changes in wireless sensors, as installing wired ones is often too costly. Here, energy harvesting technologies provide a sustainable wireless power alternative.
The Role of Technology in Energy Optimization
Energy harvesting technologies contribute to the decentralized energy model by converting local resources such as heat, kinetic energy, and indoor light directly into power where it’s needed. While heat and kinetic energy can offer benefits in industrial settings where heat and vibrations are available from machines, indoor light is generally available in areas where there are people. This makes it an ideal choice for powering IoT sensors in buildings.
Although self-powered sensors represent just one strategy for tackling the significant challenge of reducing the world’s carbon footprint, they play an essential role in sectors such as building management, especially considering that the building sector is one of the biggest contributors to global CO2 emissions.
