太陽(yáng)能發(fā)電是一種極具發(fā)展?jié)摿Φ牡吞寄茉醇夹g(shù)。因此，將全球太陽(yáng)能發(fā)電能力大規(guī)模擴(kuò)大到幾太瓦的規(guī)模，很可能是緩解氣候變化風(fēng)險(xiǎn)的可行戰(zhàn)略的重要組成部分。近年來，太陽(yáng)能發(fā)電裝機(jī)容量快速增長(zhǎng)，技術(shù)、價(jià)格和性能都有了很大改善，創(chuàng)新的商業(yè)模式也得到發(fā)展，這些都刺激了對(duì)住宅太陽(yáng)能系統(tǒng)的投資。盡管如此，還需要進(jìn)一步的進(jìn)步，才能以社會(huì)可接受的成本大幅度增加太陽(yáng)能的貢獻(xiàn)。實(shí)現(xiàn)太陽(yáng)能的這一作用最終將要求太陽(yáng)能技術(shù)在成本上具有與化石發(fā)電的競(jìng)爭(zhēng)優(yōu)勢(shì)，并在二氧化碳(CO2)排放方面受到適當(dāng)?shù)膽土P，同時(shí)——極有可能——大幅削減補(bǔ)貼。
Solar electricity generation is one of very few low-carbon energy technologies with the potential to grow to very large scale. As a consequence, massive expansion of global solar generating capacity to multi-terawatt scale is very likely an essential component of a workable strategy to mitigate climate change risk. Recent years have seen rapid growth in installed solar generating capacity, great improvements in technology, price, and performance, and the development of creative business models that have spurred investment in residential solar systems. Nonetheless, further advances are needed to enable a dramatic increase in the solar contribution at socially acceptable costs. Achieving this role for solar energy will ultimately require that solar technologies become cost-competitive with fossil generation, appropriately penalized for carbon dioxide (CO2) emissions, with — most likely — substantially reduced subsidies.
