What is High Voltage Direct Current (HVDC)?

High Voltage Direct Current, or "HVDC" power lines have the ability to transmit large amounts of power over long distances with lower capital costs and much lower electrical losses than typical AC power lines. 

What are the Advantages of High Voltage Direct Current Transmission Lines over the Standard AC Power Lines?

High Voltage Direct Current power lines have several distinct advantages over the typical AC power lines.  

High Voltage Direct Current, or "HVDC" power lines have the ability to transmit large amounts of power over long distances with lower capital costs and much lower electrical losses than typical AC power lines. 

Depending on the voltage level and construction details, losses for HVDC are about 3% per 1000 km. 

High-voltage direct current transmission allows use of energy sources remote from load centers.

In a number of applications High Voltage Direct Current, HVDC is more effective and efficient than AC transmission lines. 

Examples where HVDC is more effective, and efficient, than AC power lines, include the following:

*  Undersea cables, where high capacitance causes additional AC losses.

*  Endpoint-to-endpoint long-haul bulk power transmission without intermediate 'taps.'  

*  Increasing the capacity of an existing power grid in situations where additional wires are difficult or expensive to install. 

*  Allowing power transmission between unsynchronized AC distribution systems. 

*  Stabilizing a predominantly AC power-grid, without increasing maximum prospective short circuit current. 

*  Reducing line cost since HVDC transmission requires fewer conductors (i.e. 2 conductors; one is positive another is negative) 

*  Long undersea cables have a high capacitance. While this has minimal effect for DC transmission, the current required to charge and discharge the capacitance of the cable causes additional I2R power losses when the cable is carrying AC. In addition, AC power is lost to dielectric losses.

*  High Voltage Direct Current transmission lines can carry more power per conductor, because for a given power rating the constant voltage in a DC line is lower than the peak voltage in an AC line. 

*  Increased stability of power systems - because High Voltage Direct Current transmission lines allow power transmission between unsynchronized AC distribution systems, it can help increase system stability, by preventing cascading failures from propagating from one part of a wider power transmission grid to another. Changes in load that would cause portions of an AC network to become unsynchronized and separate would not similarly effect a DC link, and the power flow through the DC link would tend to stabilize the AC network. The magnitude and direction of power flow through a DC link can be directly commanded, and changed as needed to support the AC networks at either end of the DC link. This has caused many power system operators to contemplate wider use of HVDC technology for its stability benefits alone.


Disadvantages of High Voltage Direct Current Transmission Lines

The required static inverters are expensive and have limited overload capacity. At smaller transmission distances the losses in the static inverters may be bigger than in an AC transmission line. The cost of the inverters may not be offset by reductions in line construction cost and lower line loss.

In contrast to AC systems, realizing multi-terminal systems is complex, as is expanding existing schemes to multi-terminal systems. Controlling power flow in a multi-terminal DC system requires good communication between all the terminals; power flow must be actively regulated by the control system instead of by the inherent properties of the transmission line.

What is Energy Resource Planning?

The purpose of Energy Resource Planning (ERP)seeks to utilize and integrate the requisite analytical concepts and tools necessary to approach the problems of planning for an adequate energy supply and demand balance at the local, regional and national levels.  With a greater focus on reducing and eliminating greenhouse gas emissions, there is an increasing emphasis on "Carbon Free Energy" and "Pollution Free Power."  Renewable energy resources and renewable energy technologies are viewed as the preferred path forward for providing for energy supply and demand in conjunction with Demand Side Management.

What is the "Transmission Superhighway"?

The Transmission Superhighway, also referred to as a Green Transmission Superhighway, is the name used for the future transmission power lines that would carry green electricity from the many solar power plants and solar power parks and wind farms that generate the power, typically in remote areas, to the "load centers" or major cities that would use the green power. 

Quite simply, our out-dated and inefficient National Electric Grid, lacks the ability to carry all the new green electricity being planned from hundreds of new solar power parks and wind power generation facilities.

Building a national Transmission Superhighway would help jump-start the renewable energy investments in solar power parks.  Thousands of megawatts of new solar power parks (both Concentrating Solar Power plants and Photovoltaic Power Plants) are being planned. Most are  located in the desert Southwest due to the solar energy resource. A national Transmission Superhighway is needed to move the large amount of power, which is fairly concentrated, to the rest of the nation.  Without the new Transmission Superhighway, it would be impossible to distribute the green power to the nation. 

The new Transmission Superhighway is significantly more efficient than the present, nearly 100 year old technology that makes up our present electric power transmission and transmission and distribution network of how we get the power from central power plants to customers and major load centers.

Much of the new Transmission Superhighway will be comprised of "High Voltage Direct Current" transmission lines which is significantly more efficient than the present high voltage alternating current transmission lines.  

The new Transmission Superhighway will provide economic development, thousands of new jobs, and significantly reduce greenhouse gas emissions.

What would the new Transmission Superhighway look like?

How we make and distribute electricity is changing! 

The electric power generation, transmission and distribution system (the electric "grid") is changing and evolving from the electric grid of the 19th and 20th centuries, which was inefficient, highly-polluting, very expensive and “dumb.”  

The "old" way of generating and distributing energy resembles this slide:

The carbon clock tracks total carbon dioxide emissions in metric tons since 1750.

Since 1750, humans have emitted over 5 trillion pounds of carbon dioxide into the atmosphere. Roughly half of this has ended up in the oceans where it is beginning to damage the coral reefs. The other half is still in the atmosphere and causing global warming. Each pound of CO2 takes up as much space as a 500 pound person.

The formula (which should be good for a year or two) is:
C(t) = 2.58 ×1012 + 1240×t, where t is seconds since the start of 2007.

C is tonnes (metric tons) of carbon dioxide emissions.
2205 x C gives pounds of carbon dioxide emissions.

That comes to over 43 billion tons/year or over 86 trillion pounds/year.

Carbon dioxide (2) = 1 carbon atom with 2 oxygen atoms.
Carbon has relative weight 12 and Oxygen 16.
So it takes only 12 pounds of carbon to make 12+16+16 = 44 pounds of CO2.

Greenhouse Gas Emissions Linked to 
the Loss of a "Few" Polar Bears

This Means that 65% of America's Energy Supplies are Now Imported from Suppliers from Foreign Countries.  

Simply put, about 65% of the gasoline in your car's gas tank, comes from a foreign country.

EVERY day, the U.S. must IMPORT over 13 million bbls of oil from foreign countries and foreign suppliers to meet demand. 

At $80/barrel of oil, this also means that $1,040,000,000.00 American Dollars leave our country, EVERY DAY, to foreign countries/suppliers of our fossil fuels, to pay for the energy we need. 

That's $1 Billion EVERY day leaving our economy, and going to support a foreign country's economy. 

Talk about our foreign trade deficit..... nearly $400 Billion each year, leaves our country to pay for our oil addiction and the energy we need.  To be exact, that's $379,600,000,000.00 American Dollars.

This is NOT acceptable.

America needs to quickly transition to Energy Independence. 

Renewable Energy is the Only Way America Can Achieve Energy Independence. 

Millions of new and sustainable American jobs would be created here at home, if we would end our addiction to foreign fossil fuels, and quickly transition to an economy based on renewable energy and renewable fuels, produced here in the U.S.A. 

The good news is that today, America already has all of the Renewable Energy Resources and Renewable Energy Technologies needed to make American Energy Independence a reality. 

According to Monty Goodell, Founder and Chairman of the Renewable Energy Institute, "our increased dependence and reliance on foreign energy supplies represents a Clear and Present Danger to our national security, our economy, and the lives and livelihood of every American. Energy - including the energy we use from imported fossil fuels, is the very "lifeblood" of the American economy as it is for every industrialized country.  An economy dies without it's lifeblood of energy. This Clear and Present Danger we face is far more serious than the problems related to greenhouse gas emissions.  And while greenhouse gas emissions are very serious issue, in the long-term, pales in comparison to America's vital national security interests and America's economic stability in the short term.  For this reason alone, America needs to transition away from its addiction to foreign energy supplies. And America's abundant renewable energy resources such as the energy we receive from the sun, and renewable energy technologies such as concentrated solar power (CSP) plants - can supply 100% of America's power requirements with a concentrating solar power plant measuring 75 miles by 75 miles, located in the Southwest U.S.  By generating America's power from concentrating solar power plants, America resolves its' short-term Clear and Present Danger as it relates to importing its energy from foreign countries, and the long-term problems relating to greenhouse gas emissions."

Continuing, Mr. Goodell states that "too many Americans have forgotten what happened to us in 1973, when the Arabs and OPEC brought the United States economy to a screeching halt during the OPEC Oil Embargo.  This happened because they (mainly the country of Saudi Arabia) disagreed with our foreign policy and is the reason why they "turned off the tap" of our need for their oil supplies. When Saudi Arabia and OPEC stopped the vital flow of oil to our country in 1973, they caused an "oil shock" that severely and negatively impacted our economy. 

Mr. Goodell's question for us to ponder is, "do these countries who sell us 60% of our daily energy requirements, like us and our foreign policy, or might they leverage our addiction to their fossil fuels, and turn off the tap to make us adjust or revise our foreign policy??  Like any addict, America's foreign policy may be held hostage to its addiction, and in this case, our addiction to foreign oil, may over-ride our national interests."

Have American's forgotten the gas shortages and long lines at 
their gas stations to get gas during the Arab Oil Embargo of 1973? 

"Apparently so."  Mr. Goodell states that "in 1973, America was 'addicted' and 'over the barrel' of foreign oil to the amount of 40%.  Forty percent of our energy 'needs' in 1973 came from countries - many of which didn't like us then, and I'm afraid, many of them still don't.  The difference between 1973 and today - is that today we receive 50% MORE foreign oil now than we did in 1973.  And now we know about the problems relating to greenhouse gas emissions that we didn't know then.  America needs to change course, and change course now, in terms of its' energy supplies and how we keep America's economy strong, without the threat of being held hostage to a middle-east tyrant or regime, that could once again, turn on us, and turn off our supply of foreign oil." 

Remember ????

" Sadly," Monty Goodell continues, " most Americans have forgotten the long lines of people waiting in their cars - lined up and waiting for gasoline at their nearby gas station, with lines that were many blocks long.  And, after waiting 4-5 hours, many even waiting overnight in many places, to finally take their turn to fill up their car with gasoline, only to find that the gas station had run out of gas." 

"Let me Repeat.... That was 1973 when we imported 40% of our daily energy requirements in the form of crude oil from overseas, and from foreign countries - and many of these from countries that don't like us.

Today, over 35 years later, America has yet to learn the lesson.  We cannot continue our reliance on energy from foreign countries that supply us with 60% of the crude oil that our refineries use as a feedstock for producing gasoline and diesel fuel for our cars and trucks comes from overseas. 

America is "over the barrel" and it's not our barrel, but the barrels of oil that we are addicted by and owned by other countries.  Why have we not learned the lessons we needed to learn in 1973 when we were cut-off from the vital energy supplies we need? 

Countries like China, are growing rapidly, and have an insatiable need for crude oil. China, with their booming economy, is increasingly growing in its clout and control over international supplies of crude oil - whether they do this through their ability to buy as much oil as they need on a daily basis, or whether they simply but American drilling rigs, technology, and explore and produce oil and gas from their own fields. China, is buying large amounts of oil for their country, and causing upward pricing on declining supplies. What happens if Russia, with all of their oil and natural gas, along with China and Venezuela, with or without the help of OPEC, decided to NOT sell oil to us????

To be sure, greenhouse gas emissions are a problem, and to some, greenhouse gas emissions are also a Clear and Present Danger, but not to the extent that it presents an imminent Clear and Present Danger. 

America's reliance for 60% of our energy "needs" coming from foreign suppliers is un-acceptable.

The "driver" to get America to begin reducing and eliminating fossil fuel use should be our nation's national security and the welfare and safety of its citizens. And this can all begin with developing and investing in our own renewable energy resources and renewable energy technologies, let's start by putting solar on every rooftop that has a clear and unobstructed view of the Southern sky. See www.RooftopPV.com  or  www.DistributedPV.com  for more information.  Let's create incentives begin with adopting a national "Feed In Tariff" as Germany did in 1990. 

We simply do NOT have the luxury of time on our hands.  We need to end our dependence and reliance on foreign fossil fuels, especially from countries that don't like us! We need to rapidly begin expanding renewable energy resources and renewable energy technologies from our vast and abundant renewable energy resources, such as; solar, solar energy systems, solar cogeneration, solar trigeneration, "solar on every roof," along with; Biomass Gasification, B100 Biodiesel, Biomethane, E100 Ethanol (from cellulosic, agricultural waste, sugar cane, etc., and NOT from corn), Geothermal Power Plants, Natural Wastewater Treatment, Synthesis Gas, Waste To Energy, Waste To Fuel and Wind Power Generation where it makes economic and environmental sense."
