looking at traditional electricity
00:00:02.720 00:00:02.730 generation plants it's surprising how
00:00:04.820 00:00:04.830 much energy is wasted you might say it's
00:00:07.249 00:00:07.259 alarming the US Department of Energy
00:00:09.620 00:00:09.630 says a typical coal-fired plant averages
00:00:12.499 00:00:12.509 thirty-four percent efficiency
00:00:14.180 00:00:14.190 that means one-third of the fuel it
00:00:16.849 00:00:16.859 consumes is converted into electricity
00:00:18.859 00:00:18.869 the other sixty-six percent is lost as
00:00:22.279 00:00:22.289 waste heat and often dumped into a river
00:00:24.590 00:00:24.600 Bay or vented into the sky that's a lot
00:00:28.070 00:00:28.080 of wasted energy the waste heat from us
00:00:31.220 00:00:31.230 power generation exceeds the total
00:00:33.530 00:00:33.540 national energy use in all but three of
00:00:36.220 00:00:36.230 216 countries this is a big problem and
00:00:41.030 00:00:41.040 a huge opportunity district energy
00:00:44.299 00:00:44.309 systems capture and reuse waste heat
00:00:46.930 00:00:46.940 distributing it through underground
00:00:48.770 00:00:48.780 piping to provide energy services to
00:00:51.260 00:00:51.270 buildings and cities campuses or
00:00:53.270 00:00:53.280 communities also known as combined heat
00:00:56.450 00:00:56.460 and power or CHP that recovered heat
00:00:59.660 00:00:59.670 provides space heating hot water and
00:01:01.849 00:01:01.859 process energy for buildings and cities
00:01:04.310 00:01:04.320 communities and campuses as well as
00:01:06.830 00:01:06.840 industry health care airports and
00:01:08.870 00:01:08.880 military bases it can even provide air
00:01:12.020 00:01:12.030 conditioning it's hard to justify
00:01:14.179 00:01:14.189 wasting that much thermal energy when
00:01:16.700 00:01:16.710 we're trying to limit greenhouse gases
00:01:18.590 00:01:18.600 manage budgets and create sustainable
00:01:21.050 00:01:21.060 energy systems instead of using only 34
00:01:24.410 00:01:24.420 percent of the energy district energy
00:01:26.690 00:01:26.700 with CHP routinely achieves efficiencies
00:01:29.840 00:01:29.850 of 70 to 85 percent that's why district
00:01:33.469 00:01:33.479 energy is gaining ground think district
00:01:36.170 00:01:36.180 energy is right for your city
