Swanson's law Swanson's law Swanson's law is the observation that the price of solar photovoltaic modules tends to drop 20 percent for every doubling of cumulative shipped volume. At present rates, costs halve about every 10 years. It is named after Richard Swanson, the founder of SunPower Corporation, a solar panel manufacturer. Swanson's law has been compared to Moore's law, which predicts the growing computing power of processors. Crystalline silicon photovoltaic cell prices have fallen from $76.67 per watt in 1977 to $0.36 per watt in 2014. Plotting the module price (in $/Wp) versus time shows a dropping by 10% per year.
Unstoppable Global Warming: Every 1,500 Years view of the natural cycles in the earth's climate and argue that the current warming period is not caused by man-made greenhouse gas emissions. The book begins with the earth's climate time-line, starting from the formation of the earth 4.5 billion years ago, and leading up to the Modern Warm Period. The book ends with a chapter entitled "The ultimate failure of The Kyoto Protocol", which predicts that the Protocol will be unsuccessful in curtailing emissions. It covers the localised plummeting emissions associated with the collapse of the Soviet Union and what the book says is Russia's excess amount of
