Of course it takes tools, manufactured goods, and infrastructure to access renewable energy. Same as for any other kind of energy. Of course it must be transported from where it’s produced to where it’s consumed. Same as for any other kind of energy. There’s a lot of fuzzy thining about the source of energy and the sources of fuel.
The only source of energy to this planet is the Sun. We tap it indirectly when we burn hydrocarbons created from long-dead plants that performed photosynthesis. We move up in efficiency when we use the solar-driven water cycle to drive a hydro, or the solar-driven wind cycle to spin a turbine. We use solar energy directly in a PV cell and are still only starting to learn how to tape the energy of atomic bonds. Earth has stored energy for hundreds of millions of years and the Sun keeps producing it every day.
It comes down to how much processing or conversion must be done to put solar energy into a form we can use, or that is convenient for our needs. For example, it’s tough to duplicate the energy density, cost, portability, and availability of gasoline, but in time that may change, just as gasoline replaced wood and coal as fuel sources before it. It’s important to distinguish between energy, and fuel.
“Renewable Energy Standards” generally try to move consumption “up the food chain” to more direct fuels. I don’t agree that is smart policy, instead by removing government intervention and nanny-state “help” the free market would develop new fuels at a faster pace and in response to market needs rather that simply to comply with an arbitrary standard.
Good grief, the cleaning products suck. They don’t work so why should they tell us renewable energy the ones they are pushing does?
Well, because it’s a scam.
Oh......
The sun shines on the ocean,
and it turns the water green.
The big fish eat the little fish,
it’s a bloody horrible scene.
Well, it all falls to the bottom,
tonnes of pressure smash it all down.
And it turns into petroleum,
Which makes the world go ‘round.
Everybody sing...
You sure that’s not the Poop Song?
the interesting thing is - the renewable products they are pushing do work, but only in a small insignificant way - perhaps to operate only coffee bean grinders, worldwide?
All about woody biomass (including the efficacy of biomass heat as a renewable resouce) http://users.sisqtel.net/armstrng/biomass.htm
Their cleaning products sure don’t. I have wasted some money there.
I am a Global Warming skeptic, have been from the beginning. We think Oxygen is what makes us tick but in reality it is Carbon DiOxide. Carbon Dioxide is what plants use to make ALL our food. As far as the history of the earth is concerned our atmosphere has much less CO2 than it has had for most of its existence. I'm not worried about a little CO2. That being said there is nothing wrong with renewable energy if it is cost competitive.
There is promising research that may be an answer to some of our energy woes. One of them is oil from algae. another is liquid fuel from bacteria. The benefit is that it can be grown in a relatively small area, one of the Alge strains matures in about 24hours.
I see nothing wrong with renewable as long as it is not subsidized.
Now, you sound like you’ve done your homework on this subject. Competitive cost and no subsidy from government are key issues. I view the real point of the article posted as all the current alternative energy sources are really “miscellaneous” in that, yes they all compliment oil, gas, etc, but they cannot replace those sources. Therefore, and as you state, real replacement alternatives must be pursued.
I disagree on the subsidy issue. In the case of biomass heat, we NEED to have the forests thinned and fuels reduced. Western forests are horribly overstocked and in unhealthy condition - susceptible to catastrophic wildfire that kills people, destroys homes, water quality and natural resources.
Currently, the American tax payer is paying for fuel reduction on public lands through the federal budget. Funding cannot keep up with the pace and scale that this needs to be done. Consequently, we are seeing larger and more demaging fires that are costing the American taxpayers $millions to fight.
Subsidizing the start up of new businesses that utilize biomass makes sense in establishing a market framework to offset the costs of fuel reduction. The purchase of this forest material and its utilization in biomass energy, heat and value-added products helps reduce taxpayer subsidy for fuel reduction.
Right now, medium sized cogen (Heat and power) facilities are being sized at the 15 MgW scale or below to fit supply. Where grid infrastructure in rural areas is below capacity for transmission, then biomass heat is emphasized. Pellet mills work best when located in tandem with existing sawmill operations. In N. CA, much of that infrastructure is gone. In S. CA it is gone. Once a pellet mill is established, then municipalities, schools and eventually residences can convert over to clean, efficient biomass heat, such as the furnace systems developed in Austria or the boiler systems coming in place at schools and hospitals in Oregon.
Risks and costs must balance out before an investor will invest. Right now, supply is one of the biggest risks, because environmentalists can shut down timber sale for years on some obscure technical point. Financing is also hard to come by. Also, the utilities pay nothing for biomass energy. The elctrical rates are subsidized for solar and wind.
Incentives do work. Wind, IMHO, is a waste of money, but conversion to solar has been accelerated due to incentives. As a result, so have technological improvements and reductions in costs.
Getting rural communities converted over to district, municipal and residential biomass would stimulate these economies, create energy independence, reduce massive carbon emissions due to wildfire, help save communities and forests from burning. Subsidies, as have been given in Oregon, can prime the pump to make this happen. California is lagging waaaay behind the East Coast and Oregon in the development of this technology. If Conservatives stand firm on no subsidies, we will continue to be in last place in a renewable sector that really make sense to the taxpayer’s overall bottom line.
That all sounds good, but what are the numbers behind it? Isn’t it really another “miscellaneous” alternative fuel that will not run much of anything in a big way - only the number tell the truth. And, if it’s so great why would it need to be subsidized?
It needs to be subsidized because:
(1) wood based products infrastructure has been completely dismantled in many areas so it has to be completely re-established;
(2) Wood based heat costs half of what oil based heat costs. However, the initial investment is so great, many large public users such as schools and jails and courthouses can’t convert without some sort of loan. These are important bulk customer anchors to secure a wood pellet mill;
(3) Like most things, conversion of many users in one area is more cost effective than doing them one by one. Pellet and fiurnace/boiler businesses have to have a large enough customer base to offset start-up and location costs. [Its sort of chicken and egg. Customers first to attract location.]
(4) Much of the technology is European. Only a few American system designers and manufacturers in Oregon and New England. Also, small biomass entrepreneurs are still designing new equipment to remove the material under a variety of conditions (slope, etc.) as well as a transport it over old logging roads.
(5) In some cases, it does not pencil out but is a less expensive alternative to the cost of wildfire fighting, property loss due to fires and affects on water supplies. (Cost avoidance.)
(6) Puts people to work and is cheaper than paying for all their needs. (Many forested rural communities have 20-25% unemployment.)
Sometimes accelerated change requires incentive. These rural areas do not have the market concentration or the sophistication to reach the critical mass of conversion that in necessary to push this into a purely market-driven system. Here, particularly, they need a boost.

here are some Oregon projects: http://www.sustainablenorthwest.org/resources/biomass/community-based-wood-heat/

Our northern CA County is now attempting to follow in Oregon’s footprints, but it is a tremendous battle without the incentives, financing packages, support of the air quality board, etc.
It still sounds like it’s in the “miscellaneous” category - not a viable alternative to oil, just another relatively minor source of fuel.
