Solar roads - a new potential renewable energy for Great Britain

Area of Science:

• Environmental Science
• Renewable Energy Engineering
• Materials Science

Background:

• Global warming is an escalating threat driven by anthropogenic carbon emissions from energy demand.
• Renewable energy sources, particularly solar energy, are crucial for reducing carbon footprints.
• Solar roads present an innovative land-efficient renewable energy solution by utilizing existing road infrastructure.

Purpose of the Study:

• To evaluate the feasibility and viability of solar roads as a renewable energy source.
• To assess the energy generation potential of embedding solar panels in Great Britain's road infrastructure.
• To inform future studies on solar road implementation in diverse contexts.

Main Methods:

• A quantitative approach was employed using a basic numerical model.
• Calculations considered factors such as seasonal variations, traffic volume, shading from trees and buildings, road characteristics, solar irradiance, and solar panel types.
• The study focused on the specific case of Great Britain's road network.

Main Results:

• The study estimates that solar roads could potentially supply up to 96.42% of the UK's total electricity demand.
• This finding highlights a substantially promising potential for solar road technology.

Conclusions:

• Solar roads are a viable and attractive proposition for renewable energy generation.
• Further feasibility and viability studies are warranted to explore implementation in various settings.
• The integration of solar roads can significantly contribute to reducing the UK's carbon footprint and energy demands.
