Renewable Energy Tech
Practical insights from 1 re:build session on implementing renewable energy tech in regenerative villages.
Overview
Renewable Energy Tech encompasses technologies that generate energy from renewable sources like solar, wind, water, and biomass. In regenerative village development, renewable energy technologies enable communities to generate their own power while reducing environmental impact and increasing resilience. This guide synthesizes knowledge from re:build gatherings to provide practical insights for implementing renewable energy tech in community projects.
Definition
Renewable energy technologies generate electricity or heat from sources that are naturally replenished, such as sunlight, wind, water flow, and biomass. These technologies enable communities to produce their own energy while reducing dependence on fossil fuels and conventional power grids.
Key Principles
- Nature as model: Learn from natural systems that efficiently capture and use energy
- Dynamism: Energy systems require dynamic components for efficient energy transfer
- Integration: Renewable energy tech should integrate with other community systems
- Resilience: Diverse renewable energy sources increase community resilience
- Efficiency: Optimize energy capture, storage, and use for maximum efficiency
Methods and Approaches
Nature as model: The capillaries of trees and plants respond to the movement of the moon and sun. Leaves act like solar panels, extending their tips to reach toward light, all powered by water moving through the system. Nature provides models for renewable energy systems that can inform technology design and implementation.
Dynamism in energy systems: Dynamism is important in renewable energy transfer. This includes magnets used in solar and wind turbines, electrification of vehicles, and battery technologies like LFP (lithium iron phosphate), which may be a better choice than other battery chemistries. Understanding these dynamic components is essential for effective renewable energy systems.
Solar technologies: Photovoltaic panels, solar thermal systems, and passive solar design capture energy from sunlight for electricity, heating, and cooling.
Wind technologies: Wind turbines convert wind energy into electricity, with various sizes and designs for different contexts and scales.
Battery storage: Energy storage systems (like LFP batteries) store renewable energy for use when generation is low, enabling reliable power supply.
Hydroelectric systems: Small-scale hydroelectric systems can generate power from water flow in appropriate locations.
Biomass energy: Converting organic materials (wood, agricultural waste, biogas) into energy provides renewable power while managing waste streams.
Benefits
- Energy independence: Renewable energy tech enables communities to generate their own power
- Environmental impact: Renewable energy reduces greenhouse gas emissions and environmental impact
- Cost savings: Once installed, renewable energy systems can reduce or eliminate energy costs
- Resilience: Diverse renewable energy sources increase resilience to power outages and price fluctuations
- Scalability: Renewable energy systems can scale from individual buildings to community-scale installations
- Innovation opportunities: Renewable energy tech continues to advance, creating opportunities for improved efficiency and lower costs
