Public Perception

A further major issue is whether people will find CO2 sequestration underground an acceptable alternative to emitting CO2 to the atmosphere. Research on perceptions of CCS is challenging because of: a) the relatively technical and "remote" nature of the issue, meaning that there are few immediate points of connection in the lay public's frame of reference to many of the key concepts; b) the early stage of the technology, with very few examples and experiences in the public domain to draw upon as illustrations [84]. In a UK survey of public perceptions [84], it was found that on first hearing about carbon storage in the absence of information as to its purpose, the majority of people either do not have an opinion at all or are somewhat sceptical. Once (even limited) information is provided on the role of carbon storage in reducing CO2 emissions to the atmosphere, opinion shifts considerably towards slight support for the concept. Support depends, however, upon concern about human-caused climate change, plus recognition of the need for major CO2 emission reductions. It also depends upon CCS being seen as one part of a wider strategy for achieving significant cuts in CO2 emissions. A portfolio including renewable energy technologies, energy efficiency and lifestyle change to reduce demand, was generally favoured. CCS can be part of such a portfolio but wind, wave, tidal, solar and energy efficiency were generally preferred as options. As a stand alone option, it was felt that CCS might delay more far-reaching and necessary long-term changes in society's use of energy. The notion of CCS as a "bridging strategy" to a hydrogen-based energy system was welcomed.

It was felt that uncertainties concerning the risks of CCS had to be better addressed and reduced, in particular the risks of leakage, of accidents, or environmental and ecosystem impacts, and any human health impacts.

Lenstra and van Engelenburg [60] pointed out that the current paradigm for environmental policy causes a negative reaction towards end-of-pipe solutions such as CO2 removal when they are presented as a dedicated single technology. The authors suggest that CO2 storage could be raised most appropriately as part of a wider debate along the lines of: "What do we the public think should be done about CO2 emissions to the atmosphere?"

Clewes [quoted in 60] indicates the following perceived barriers to CO2 capture and storage technology: The technology is in its infancy and un-proven, it is too costly, not enough is known about the long-term storage of CO2, the capture and storage of CO2 are seen as being energy intensive, the option presents an enormous engineering and infrastructure challenge, and it is not a long term solution. Both Lenstra and van Engelenburg [60] and Clewes [quoted in 60] conclude that these barriers can only be overcome by R & D and effective demonstration of the technology. It will not be possible to overcome them by communication alone.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
