About RF Cafe

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

U.S. Leads the Nuclear Energy Pack

Believe it or not, as of 2005, the U.S. is still the world's largest generator of commercial electrical power using nuclear energy, although as a percentage of the total national electrical energy generated, it ranks only #13 out of the top 30. In 2005, there were 103 commercial nuclear generating units operate here. In all, those power stations generate about 20% of our nation's power. I was surprised to learn that it is that high of a percentage. In December 2005 alone, 71.7 billion kWh of energy was produced by those stations, according to the Department of Energy's (DoE) Energy Information Administration (EIA).

Coal has been and continues to dominate as the primary fuel, accounting for about 40% of the world's generation. Natural gas and renewable (hydroelectric, wind turbines, etc.) sources each contribute approximately 18% of the world's total, nuclear 16%, and oil 8%.

Total energy consumption worldwide for 2005 was an astounding 26 trillion kWh. That's up from 14.3 trillion kWh in 2002. Much of the increase has been due to China's rapid industrialization. China could use more nuclear power plants to stem the rise in pollution. The major Chinese cities suffer enormously from smog now because environmental regulations are practically non-existent. As of 2004, only about 3% of China's total energy was supplied by nuclear power plants. Coal, natural gas, timber, hydro, and oil fuel the bulk of China's rising industrial power, with virtually unchecked emissions. Sure, they are signatories to the Kyoto Protocol, but do not – or do, if you live there – hold your breath while waiting for meaningful clean air regulations for be implemented and enforced since organized protestors would likely be rolled over by tanks ala the Tiananmen Square massacre.

Here is a list of countries that currently have nuclear power plants, along with the approximate portion of the country's total energy consumption provided by nuclear power. Note that many are part of the former USSR, and had established their nuclear programs before the breakup.
