@Jenny Chase : 我从事太阳能行业分析近20年,亲眼见证了其令人印象深刻的增长。太阳能组件如今价格低廉,已不再是富人的专利,其价格甚至可以与普通民用建材相媲美。全球太阳能组件安装量巨大,但数据收集存在困难,许多国家的官方数据严重低估了实际安装量。以巴基斯坦为例,官方数据显示其太阳能装机容量不足3吉瓦,但实际情况远超此数,卫星数据证实了这一点。巴基斯坦民众安装太阳能的主要原因是极端高温和高昂的电费,太阳能发电能够满足其白天用电需求,特别是空调和风扇的使用。这导致巴基斯坦的电力需求下降,并对以煤炭为主的电网造成冲击。南非的太阳能市场则经历了起起伏伏,在经历大规模停电后,太阳能安装量激增,但随着电网的修复和太阳能对电网的支撑作用增强,安装量又有所回落。总的来说,更便宜的太阳能正在帮助贫困国家满足电力需求,减少对化石燃料的依赖。在加州等电力需求相对较低的地区,太阳能已经能够取代化石燃料,并通过与电池和风能等其他可再生能源的结合,进一步减少碳排放。 @Modupe Akinola : Jenny Chase的研究强调了数据收集的挑战。为了更准确地评估太阳能的使用情况,我们可以寻找替代数据指标。例如,发展中国家煤油的使用量可能是一个很好的指标,因为煤油价格昂贵且会造成室内污染,而太阳能可以作为一种更清洁、更经济的替代能源。此外,拥有大量移动电话的家庭更有可能使用太阳能,因为有限的电网电力常常导致手机电池电量不足。这些指标可以帮助我们更好地了解现有或潜在的太阳能使用情况,即使在数据不足的情况下,我们也能看到太阳能正在对减少对化石燃料的依赖方面发挥积极作用。

Chapters
This chapter explores the drastic decrease in solar panel costs, making them accessible to a wider population. It contrasts the past perception of solar panels as a luxury item with their current affordability and widespread use, emphasizing their role in combating climate change.
  • Solar panels are now as cheap as eight cups of expensive coffee.
  • Solar power is becoming affordable and accessible, displacing fossil fuels in many countries.
  • The growth of the solar industry is impressive, with significant installations worldwide.

Shownotes Transcript

How prevalent is solar power, really? According to researcher Jenny Chase, it's already displacing fossil fuels in key energy markets around the world. She explains the rise of affordable solar power and dives into how her team tracked its rapid installation in unexpected countries, offering a vision of a brighter, more sustainable future. After the talk, Modupe looks to data on kerosene use in developing countries as a viable indicator for a potential shift to solar energy.
