Challenges and Requirements for Upgrading Power Lines for Renewable Energy

This chapter discusses the challenges and requirements for building and upgrading high voltage power lines to accommodate the increased electricity demand from decentralized renewable sources. It highlights the need for a significant amount of copper for the infrastructure, including wiring in houses, solar and wind farms, and electric vehicles. The chapter also mentions the delays in power transmission cable projects and the potential increase in demand for high voltage cables for offshore wind projects. The shortage of transformers and grid components, as well as the difficulties and costs of mining for more copper, are also addressed.
