Jenny Chase 认为,德国2004年实施的'上网电价'政策是太阳能价格下降的关键因素,它促进了太阳能产业的大规模发展,并使得在田野上建立太阳能发电站成为盈利项目,推动了太阳能产业的商业化发展。'上网电价'政策保证了太阳能项目的现金流,使得银行更容易向这些项目提供贷款。中国企业从一开始就参与了太阳能产业,并在价格下降的过程中发挥了重要作用,中国形成了一个完整的太阳能产业链,这促进了产业的快速发展和成本的降低。太阳能电池板的价格下降遵循经验曲线定律,即随着生产经验的积累,成本会持续下降。 此外,Jenny Chase 还分析了储能技术、电网建设以及美国太阳能市场发展等问题。她认为,在季节性气候变化明显的地区,仅依靠太阳能和电池储能难以满足全年的电力需求,需要长效储能技术来解决电力供应问题。为了适应分布式能源系统,需要对电网进行大量投资,以提高其效率和输送能力。美国太阳能发电发展缓慢,部分原因是受到贸易战和审批流程的影响,以及与中国的贸易战导致太阳能电池板价格高昂。 最后,Jenny Chase 还分享了她对未来能源发展的展望,她对全球能源转型持乐观态度,并预测未来20年发展中国家将广泛采用太阳能发电,并需要加强电网建设以适应分布式能源系统。 主持人 梳理了太阳能价格下降的历史,并探讨了其对全球能源转型的影响。过去20年,太阳能电池板价格下降了97%以上,导致太阳能发电成本大幅降低。太阳能发电成本低廉且资源丰富,虽然不能解决所有气候问题,但能解决很多问题,并带来新的机遇。预计到2030年,在阳光充足的地区,太阳能发电将基本免费。在加利福尼亚等地区,由于太阳能发电的增长,白天电力供应超过需求,导致电价下降甚至为负,应对白天电力过剩的最佳方案是向用户提供免费或低价电力,鼓励用户增加用电量。

Deep Dive

Chapters
The extraordinary decline in the price of solar panels by over 97% in the past 20 years has transformed the energy landscape. This chapter explores the initial key moments that kickstarted the solar power revolution, including the German feed-in tariff policy.
  • Solar panel prices fell by more than 97% in the past 20 years.
  • The German feed-in tariff policy in 2004 was a pivotal moment for solar power.
  • Solar power installations have grown exponentially, with more solar power installed in the past two days than existed in the whole world in 2004.

Shownotes Transcript

In the past 20 years, the price of solar panels has fallen by more than 97 percent. This extraordinary decline is good news for the world – and it’s transforming the way energy is produced and consumed.

For the next few episodes, we’ll be talking to people who are in the middle of this solar power revolution to find out how it happened, and what it will mean for the world.

Today, Jenny Chase, the author of Solar Power Finance Without the Jargon, tells the story of how solar power got so cheap and where it’s exploding today, and she explains what problems we still need to solve to pull off a worldwide energy transition.
