Electricity has been the unspoken bedrock of modern life. Decisions about how power is produced, transmitted, and delivered have been entrusted to technical experts and have been relatively unquestioned. In turn, the electricity sector has historically been an opaque one, impervious to public scrutiny. Yet liberalization of the sector, global and local environmental impacts, and new energy technologies are spurring a growing clamor to peel back the layers of technocracy and to prise open a space for new voices and actors. This article explores the ways in which the governance of the electricity sector is changing and being changed by a new politics of energy production and consumption. The article focuses on long‐term electricity planning to understand how critical independent experts and nonexperts have formed alliances that challenge entrenched decision‐making processes and assumptions. It presents case studies from South Africa and Thailand that document the struggle between reluctant departments of energy and nongovernmental initiatives demanding access to the processes underpinning the production of knowledge about electricity sector needs. The analysis places these cases within the shifts under way in energy sectors around the world, away from centralized command‐and‐control systems to those that are decentralized with multiple points of energy generation. It explores the implications for how governance is conceived, with special attention to the implications for both policy and activist agendas. What forms of interaction between experts and citizens can we conceive, and how can they be supported?
Solar energy is commercially exploited to provide benefits in the form of various products and capabilities applying a range of technologies. Electricity generation is achieved either directly from photovoltaic cells made of various materials or indirectly through the steam production from concentrating solar thermal systems. Whereas solar thermal power generation requires large scale plants, photovoltaic systems can be large or small in scale and building integrated, if required. Both types of generation can be standalone or connected to power grids. Solar energy is also extensively used for water and space heating, cooling and drying purposes. It can also be stored and/or transformed into a range of clean fuels and contributes energy to the manufacture of various energy-intensive products. The research into the artificial photosynthetic synthesis of biofuels although encouraging is, however, yet to be achieved commercially exploited on a large scale. Much scope remains for innovative technology breakthroughs to further improve the efficiency and uptake of all the solar energy technologies currently exploited or under investigation. Policy frameworks, renewable portfolio standards, feed-in tariffs and net-metering play an important and ongoing role in promoting the uptake of photovoltaics in particular.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
