Life, as many people know it, would not be possible without access to cheap and abundant energy. More than 85% of the world's energy comes from the combustion of oil, coal and natural gas. Scientists generally agree that the combustion of fossil fuels is causing warming of Earth's climate and having deleterious effects on the environment. Many fear that climate change will lead to coastal flooding, an increase in the prevalence of vector- and water-borne infectious diseases, and conflict over fossil fuels, water and food. Clearly, action is needed.
Reducing our consumption of energy and adopting a more frugal lifestyle could be the first steps, but they cannot be the only strategies. The fossil fuels that remain must be used more effectively and other energy sources need to be identified, preferably ones that are climate neutral. The Reviews in this Insight cover a small fraction of the various scientific and engineering endeavours that may eventually deliver the technological innovations to harvest energy from alternative sources.
The Reviews clearly show that there are many energy solutions to be explored. These possible strategies range from the well-established photovoltaics to nascent methods, such as the use of algae to produce potential fuels. However, we still have a long way to go before approaches such as those covered in this Insight can compete in earnest with conventional energy sources. We hope that the articles that appear in the following pages will inspire young scientists and engineers to join the quest to secure a sustainable-energy future.

Apparently "Nature carries sole responsibility for all editorial content and peer review" but as ever, a commercial enterprise like Nature will be unwilling to bite the hand that may feed it again in the future. When will we see a detailed review of the peer-reviewed literature on peak oil rather than Chu & Majumdar's paper stating, "Although the consumption of oil has increased by 31% between 1980 and 2008, the known reserves have increased comparably owing to improvements in exploration and extraction technologies"? Others would contend that we are now consuming oil at a rate four-fold that of discovery. And, in any case, the issue with peak oil is that it is about the rate of production, not the size of the reserve base. The world?s remaining oil is, on the whole, more difficult to produce meaning that it requires greater energy inputs/monetary investment. The world?s economy is powered by energy flow, not energy reserves so it we cannot maintain the flow rate we will see economic contraction.
