The only thing that really scales up apart from nuclear is solar power from other people's deserts. David J. C. MacKay More Quotes by David J. C. MacKay More Quotes From David J. C. MacKay It sounded like a very loud vacuum cleaner behind us. David J. C. MacKay vacuums loud behinds We can't be anti-everything - we need an energy plan that adds up. But there's a lack of numeracy in the public discussion of energy. Where people do use numbers, they select them to sound big and score points in arguments, rather than to aid thoughtful discussion. David J. C. MacKay thoughtful numbers people In a climate where people don't understand the numbers, newspapers, campaigners, companies, and politicians can get away with murder David J. C. MacKay future numbers people If all the ineffective ideas for solving the energy crisis were laid end to end, they would reach to the moon and back David J. C. MacKay energy moon ideas The bottom line in 2007 is that enrollment costs are going up substantially, drug coverage is declining and the brand name coverage in the doughnut hole is being eliminated... Medicare D is an insurance program, not a benefit. As consumption increases, so too will cost. The changes in 2007 clearly demonstrate the limitations of the program. David J. C. MacKay cost drug names We must not let ourselves be swept off our feet in horror at the danger of nuclear power. Nuclear power is not infinitely dangerous. It's just dangerous, much as coal mines, petrol repositories, fossil-fuel burning and wind turbines are dangerous. David J. C. MacKay nuclear feet wind When the Industrial Revolution started, the amount of carbon sitting underneath Britain in the form of coal was as big as the amount of carbon sitting under Saudi Arabia in the form of oil, and this carbon powered the Industrial Revolution, it put the 'Great' in Great Britain, and led to Britain's temporary world domination. David J. C. MacKay industrial-revolution big great world The discussion about energy options tends to be an intensely emotional, polarised, mistrustful, and destructive one. Every option is strongly opposed: the public seem to be anti-wind, anti-coal, anti-waste-to-energy, anti-tidal-barrages, anti-carbon-tax, and anti-nuclear. David J. C. MacKay about discussion emotional energy I would like to help people have honest and constructive conversations about energy. We need to understand how much energy our modern lifestyles use, decide how much energy we would like to use in the future, and choose where we will get that energy from. David J. C. MacKay understand future energy people All renewables, much as I love them, are diffuse. They all have a small power per unit area, and we have to live with that fact. David J. C. MacKay live small power love I was writing a book about sustainable energy, and a friend asked me, 'Well, how much energy do you use at home?' And I was embarrassed. I didn't actually know. David J. C. MacKay me you home book I was distressed by the poor quality of the debate surrounding energy. I was also noticing so much green wash from politicians and big business. I was tired of the debate - the extremism, the nimbyism, the hair shirt. We need a constructive conversation about energy, not a Punch and Judy show. I just wanted to try to reboot the whole debate. David J. C. MacKay tired green quality business Most of physics is about energy, and physicists understand inefficiencies. I wanted to write a book about our energy options in a neutral, human-accessible form. David J. C. MacKay understand physics energy book The amount of energy saved by switching off the phone charger is exactly the same as the energy used by driving an average car for one second. David J. C. MacKay phone driving car energy Electric cars are really very cool. Air-source heat pumps are great. David J. C. MacKay electric-cars great cool heat Solving climate change is a complex topic, but in a single crude brush-stroke, here is the solution: the price of carbon dioxide must be such that people stop burning coal without capture. David J. C. MacKay solution climate-change change people To have constructive conversations about the world's energy options, one needs to take a calm look at the numbers. David J. C. MacKay look calm energy world The United States consumes power per land-area at a rate three times the average. Even though they are more energy efficient, densely populated industrial countries like Germany, Britain and Japan have even bigger power consumption per area. David J. C. MacKay like three energy power Fridges can be modified to nudge their internal thermostats up and down just a little in response to the main's frequency in such a way that, without ever jeopardising the temperature of your butter, they tend to take power at times that help the grid. David J. C. MacKay your down power way Fusion power is speculative and experimental. I think it is reckless to assume that the fusion problem will be cracked, but I'm happy to estimate how much power fusion could deliver, if the problems are cracked. David J. C. MacKay problems think power happy
