If we constructed solar farms at the same rate, we would be finished in 3 years. The USA would require a much larger area and approximately 1,000 of these super-sites.Īccording to the United Nations 170,000 square kilometers of forest is destroyed each year. If the UAE constructed the other 7 km per side of that area, it would be able to power itself as a nation completely with solar energy. The UAE has plans to construct 1,500MW of capacity by 2020 which will require a space of 3 km per side. If divided into 5,000 super-site installations around the world (average of 25 per country), it would measure less than 10km a side for each. At first that sounds like a lot and it is. This is roughly equal to the area of Spain. h per square meter (198,721,800,000,000 / 400) and we arrive at 496,804,500,000 square meters or 496,805 square kilometers (191,817 square miles) as the area required to power the world with solar panels.h.ĭividing the global yearly demand by 400 kW.Therefore, we can multiply each square meter by 2,000 to arrive at a yearly kW That’s 2,000 hours per year of direct sunlight. Using 70% as the average sunshine days per year (large parts of the world like upper Africa and the Arabian peninsula see 90-95% – so this number is more than fair), we can say that there will be 250 sun days per year at 8 hours of daylight on average. We have our capacity in KW so in order to figure out how much area we’ll need, we have to multiply it by the number of hours that we can expect each of those square meters of photovoltaic panel to be outputting the. So now we know the capacity of each square meter and what our goal is. 2KW per SM of land (an efficiency of 20% of the 1000 watts that strikes the surface in each SM of land). h per year (1/11 billion of the total world usage).As a comparison, the average household uses approximately 18,000 kW So to find this out we start with the big number 678,000,000,000,000,000 Btu.Ĭonverting this to KW We should all start wondering about these things since we will have really no other choice* by the turn of the next century. To create fuel that can be used in vehicles and equipment I am assuming that some of the electricity generated would be used to create hydrogen. I wonder what surface area would be required and what type of infrastructural investment would be required to supply that amount of power by using only solar panels. We hope that with the implementation of demand-side efficiency measures worldwide, long-range estimates will prove to be overestimated.Īccording to the US Department of Energy ( Energy Information Administration), the world consumption of energy in all of its forms (barrels of petroleum, cubic meters of natural gas, watts of hydro power, etc.) is projected to reach 678 quadrillion Btu (or 715 exajoules) by 2030 – a 44% increase over 2008 levels (levels for 1980 were 283 quadrillion Btu and we stand at around 500 quadrillion Btu today in 2009). The IEA has updated estimates since 2009, but the overall trends are the same. Licensed under Creative Commons CC BY-NC-ND

For large scale factors, you might see less-than-beautiful text rendering, but the size is what you would expect-neither rounded up nor down to the nearest font size supported by Windows or Linux.Note in 2021: We have updated this information graphic in August of 2021. This results in stair-step scaling of text.īut the geometricPrecision property - when fully supported by the rendering engine - lets you scale your text fluidly. But if you request a font size of, say, 9 with a scale of 140%, the resulting font size of 12.6 doesn't explicitly exist in the font system, so the browser rounds the font size to 12 instead.
In SVG, when text is scaled up or down, browsers calculate the final size of the text (which is determined by the specified font size and the applied scale) and request a font of that computed size from the platform's font system. So this value can make text using those fonts look good. Certain aspects of fonts - such as kerning - don't scale linearly. The browser emphasizes geometric precision over rendering speed and legibility. This enables kerning and optional ligatures. The browser emphasizes legibility over rendering speed and geometric precision. The browser emphasizes rendering speed over legibility and geometric precision when drawing text. For differences in how this value is interpreted by the browser, see the compatibility table. The browser makes educated guesses about when to optimize for speed, legibility, and geometric precision while drawing text.
