In the next two decades, business people, voters, hydropower suppliers and politicians will encounter the same – or something like this – more than once: whether they should invest in technology and projects that generate electricity, or whether they should invest in solid state Energy-saving products such as lighting and dynamic air conditioning?
For pure coincidence, the comparison of LED lights with nuclear power provides a wonderful way to study this problem. In the United States, nuclear power plants account for 19% of total power generation, while lighting power accounts for 19% of total electricity use. In this way, it can be said that the existence of 104 commercial nuclear reactors in the United States is to supply lighting power. If you want to increase your effective power generation by 20%, you can either build 21 nuclear reactors or cut lighting power by 20%.
It is roughly the same in the world. Lighting power accounts for 19% of total electricity consumption worldwide, while 434 nuclear reactors worldwide account for 12.3% of total power generation. In the 20 years from 2010, global electricity consumption will climb 93%, reaching 39 trillion degrees in 2040, and the output of electric light source is expected to double, from 113 shots in 2000 (pet/peta) - To indicate 1015 times the international unit of the word head; lumen / lumens for the luminous flux unit - an increase of 217 shots to 2030. Lighting and electricity always advance and retreat together.
So, what is the most reasonable way? In advance spoiler: the light bulb is easy to win. According to estimates by the US Department of Energy, solid-state lamps are expected to cut lighting power consumption by 46%.
"By 2030, the annual end-of-life energy savings due to the popularity of LED lights will reach 300 billion kWh, equivalent to the combined annual power generation of about 50 1,000 MW power plants," the US Department of Energy estimates.
In other words, if you can put all of these expected LED lighting systems in place overnight – the only difficulty in doing this is how to find enough bulbs, you can shut down 44 nuclear reactors by the end of the year and/or Delay the construction of any new nuclear power plants for decades.
More radical initiatives will further reduce the country’s demand for nuclear power. Case studies show that combining grid control with the popularity of LED lights can cut electricity use by eight to ninety percent, or shut down 35 to 45 power plants. With intelligent lighting and computerized switches, the United States has lost the meaning of almost all nuclear reactors.
Is lighting more cost effective? Yes, and far ahead of nuclear power. Georgia Power is trying to get two nuclear reactors connected to the grid to generate electricity. The estimated budget has soared from the previous $900 million to the current $14 billion, and the project has been postponed to 2017 or 2018. Earlier in October, nuclear reactor construction contractor Westinghouse also brought Georgia Power to court.
Finland's Olkiluoto is a 1.6 GW nuclear power plant originally scheduled to be completed in 2009. It seems that it will not be connected to the grid until at least 2016.
Then use the lighting to make a comparison. Between 2010 and 2011, the cost of major component packages for LED bulbs fell from $13 per thousand lumens to $6 per thousand lumens. Lux Research predicted in 2012 that by 2020, LED bulb prices will be cut by 50%, hitting $11. Unfortunately, this has happened now. At some vendors, LED bulbs with the equivalent of 60-watt incandescent lamps are priced between $10 and $12.
