The Process For Transitioning To Renewable Energy
In the previous blog, A Call For The Transition To Renewable Energy it was discussed that industrialized nations of the world will soon have to address that a world energy crisis driven by demand from developing countries is looming within the next 25 years. Fossil fuels alone will not be able to meet demand. The easier to extract surface sources are rapidly becoming exhausted requiring more difficult and environmentally damaging drilling and mining procedures that are both more time intensive and expensive. The increased costs of energy and potential shortages can create more geopolitical stresses between countries as they scramble to meet their energy demands. It is beyond time to ramp up existing renewable energy sources (biofuels, solar thermal, photovoltaics, wind, geothermal, tidal, and biomass) to supplement fossil fuels over the next 25 years while actively searching for long term, highly efficient energy systems to transition into beyond 2035.
The liquid fuel transportation sector is dominated by petroleum which is refined into gasoline, diesel, and jet fuel. The transition process in this sector would involve escalating biofuels production in order to supplement future petroleum demand. Cellulosic ethanol can be economically derived from gasification processes and will represent the most cost effective and efficient production means of ethanol production. It also doesn’t compete against food crops, requires much less water, and can be attained from a multitude of carbon based sources including the unusable residue from crops, natural fast growing grasses and plants, disposable wood from logging, and even human waste. Increasing the additive rates of ethanol in gasoline up to E30 (30% ethanol / 70% gasoline) and providing government subsidies for fuel line conversions will contribute significantly to mitigating demand and reduce the chance of rampant price increases due to regional gas shortages.
Diesel fuel necessary for commercial transportation (large trucks and ships) can also be supplemented by biofuels, in this case utilizing bio-algae, jatropha, and halophytes to create bio-diesel. Microbial organisms can be used during the processing to increase yield and refinement efficiencies and reduce costs. Diesel blends up to B30 (30% biodiesel / 70% petroldiesel) can be attained without major modification in fuel lines. World governments can then provide similar subsides for fuel line conversions to trucking and shipping fleets. Jet fuel blends can be supplemented with bio-algae; the U.S. military and some commercial airlines have already taken keen interest and developed prototypes for this application. The goal is to supplement petroleum based diesel and jet fuels with biodiesel which will mitigate demand and reduce the chance of price increases in commercial transportation which adversely affects consumer goods pricing and airline ticket prices.
In addition, supplementing petroleum based fuels should be done in unison with the generation of new hybrid (gasoline/battery) or completely battery based automobiles and light truck production over the next 25 years. Battery technology and high capacitance systems need to be elevated in importance and additional government funding for research and development put in place to provide economically viable batteries and ultra capacitors with greater yields and longer life capabilities. If necessary the patents held by the fossil fuel and aerospace defense industries need to be made available for public use instead of being put on ice as a potential threat of substitution to petroleum, or classified for military uses. Suitable battery technology may very well already exist but the public sector does not have access to it. Utilization of hybrid, battery, or high capacitance system will further reduce future demand for liquid petroleum fuels but will require increased demand in electricity production. Heavy trucks, trains, and ships used for commercial transportation require considerable power to move heavy loads. Battery and high capacitor systems are not currently able to provide adequate power to solely meet commercial transportation needs. They will be more reliant on hybrid systems and will require more energy from the biodiesel / petroldiesel blends than are required for cars and light trucks.
The unspoken and long term strategic goal of many developed countries appears to be to use up the petroleum resources of other countries while saving their own reserves for emergency or to sustain their countries liquid fuel needs decades from now. This strategy needs to be scrapped and replaced with a new 25 year goal that includes drilling and refining the readily available global petroleum resources in combination with increases in cellulosic ethanol and biodiesel production, government subsidization for replacing fuel lines on existing personal and commercial vehicles, and creating high efficiency hybrid, battery and high capacitance electric cars and light trucks for personal transportation, and hybrid biodiesel large trucks, trains and boats for commercial uses. Then by 2035, begin the process of transitioning into hydrogen fuel based transportation models for developed countries, while allowing undeveloped countries additional time to become petroleum independent. This means limiting expensive and risky deep water drilling rigs, shale extraction, and production of more oil refineries limited only to petroleum. All government subsidization for the petroleum sector should cease and be transferred to companies generating second (cellulosic ethanol), third (bioalgae), and fourth (high yield genetically modified plants combined with microbial catalysts) generation biofuels, and for the development of biofuel infrastructure. This would include refineries that can be utilized for both petroleum and biofuels.
Resistance from the very profitable petroleum sector will be considerable and OPEC nations will put up a strong fight even going so far as to temporarily drop oil prices in order to draw attention away from the need to transition to renewables and to save the petroleum industry’s future profitability. Excuses for why renewables are a panacea will flourish and will need to be set aside. Our next generation of automobiles may not run as fast, or have the same mileage capability, but they will be clean and reduce our reliance on a polluting fuel source that has created enough geo-political instabilities and wars already. This 100 year old technology is past its prime and the world is certainly capable of doing better. The reason fossil fuels have been held in place this long as our dominate source of energy is because of the massive profitability and wealth generation it provides for a small percentage of the world’s population and not for its current benefit to humanity.
The other half of the fossil fuel equation is electricity production which is provided by coal and natural gas. Electricity production actually requires more fossil fuels than the transportation sector and demand is projected to outpace petroleum and will be further increased by the need for hybrids, electric, and high capacitance vehicles all of which will draw additional power from the grid. The transition of this sector, over the next 25 years, should be a move towards the existing renewable energy sources of solar thermal, photovoltaic, wind, tidal, geothermal, and biomass facilities. Biomass which uses carbon based refuse (forestry, crop, animal, and industrial) and wastes (sewage and municipal solid) will be the only source that requires commodity based replenishment that could be subject to price fluctuations, but this resource will be derived from throw away material. The transition process itself can begin with the removal of coal and natural gas subsidies and strict limitations on future coal or natural gas power plant production. One such limitation could require no more coal fired plants built without adjacent bio-algae photo bioreactors for algae based biodiesel production and CO2 sequestration. Instead, funds could be allocated to infrastructure development of large solar thermal, geothermal, tidal and wind generation systems. Subsidies should also be provided to business and homeowners to put photovoltaic arrays on their premises. If regional electricity service providers heavily vested in coal and natural gas production want to continue as public electricity providers they will need to be required to build an increasing number of energy facilities that are completely renewable in nature. Some renewable energy plants are more expensive to construct than traditional coal and natural gas facilities, certainly the case for large solar thermal operations. However, over the 25 year life span of the facility the infrastructure costs become offset within a few years since there are no ongoing requirements for expensive and environmentally damaging drilling, mining, refining, and distribution expenses associated with acquiring oil, coal, and natural gas. Renewable energy power plants will be cheaper for developed and developing countries in the long run, providing clean energy, and not require purchasing or extracting fossil fuel commodities from potential hostile countries.
Synergies exist between complimentary renewable energy sources and with existing fossil fuel sources. Large megawatt solar thermal facilities can be designed to provide power for cities, or smaller solar thermal power plants can be utilized for neighborhood or suburb electricity generation. Residential and commercial photovoltaic arrays with government subsidies to assist business and resident affordability can be utilized in conjunction with solar thermal (or other renewable energy sources) to help reduce the regions demand. Solar thermal, geothermal, and wind farms can share space with bio-algae photo bioreactors (PBR’s) to reduce land costs and reduce space requirements. Biofuels can be generated from sewage, waste material, food crop residue, and wood residues creating fuel sources from material that would otherwise be burned or sent to landfills. Fast growing and drought resistant plants requiring little irrigation can be grown and harvested on lands unsuitable for crops and utilize husks, stovers, and other discardable material from traditional crop harvesting. All existing coal fire and natural gas plants could have bio-algae PBR’s in place to absorb the CO2 that would otherwise be released into the atmosphere. In developed countries all new power plants should be renewable where possible and only natural gas if not. Coal plants should only be considered for poorer developing countries with large coal reserves.
A new paradigm for worldwide renewable energy production can be implemented where profitability expectations are removed from future State owned and privately held renewable energy companies. In countries with a private sector, existing renewable energy companies could be incentivized by their governments to switch to a strictly non-profit model. Another option is the creation of new private non-profit renewable energy companies with infrastructure development and scaling subsidies provided by their governments that would allow them to provide energy at lower costs to consumers and compete directly against for-profit renewable energy (and fossil fuel). If full government subsidization is not possible then 0% infrastructure and scaling loans could be made available with repayment plans established that assure competitive energy pricing remains available to the public. State owned energy companies with little incentive to eliminate their profit structure will still be able to provide energy indigenously and to the developing nations but in time will be hard press to remain competitive outside their own borders.
The goal of the non-profit renewable energy provider is to be able to produce and distribute electricity in the most efficient and low cost manner possible and to pass those savings onto their customers. It is also to provide energy sector jobs to replace those jobs lost from the fossil fuel industries. Favorable government legislation and subsidization for private sector non-profits will be essential to ensure political barriers to entry are removed and to meet infrastructure costs and to develop economies of scale. Subsidization can come from removing subsidies provided to very profitable oil, coal and natural gas companies and from tax revenues associated with providing clean energy. A non-profit model focused on efficiency and removing unnecessary expenses associated with pay for performance executive compensations, investor ROI expectations, profits for mining and drilling operations, costs related to exporting of fossil fuels, and short sighted profit maximizing decision making will be removed from the future energy equation. I am not advocating government takeover of the western energy industry, but the establishment of true non-profit private companies in the free market economies. For already established state owned companies heavily vested in fossil fuels my hope is they will eventually operate under the same non-profit guidelines as they to transition towards renewable. This should also decrease geo-political instability in certain regions of the world that use energy profits to sponsor terrorism or as funds to support military buildup and wars.
It is time for world governments especially those in developed countries with free market to start acting responsibly and considering its citizens. Energy is a basic requirement for all societies and the world has been limited to technology and policies that are outdated and no longer in its best interests. The question of how to pay for the transition to renewable energy is legitimate. Whether governments should increase taxes or use existing tax dollars to subsidize renewable energy infrastructure and provide assistance for companies to scale up production will be debate and heavily resisted from many channels. Interestingly enough, funding didn’t appear to difficult to acquire when it was necessary for bailing out irresponsible financial companies or providing massive subsidies to the ridiculously profitable fossil fuel industry. Fossil fuel based companies know they will eventually have to venture into the renewable market as oil, coal, and natural gas become to scarce or expensive. Why should the world wait until governments are near financial collapse due to high energy costs affecting nearly every sector of their economies, or countries are on the brink of war due to scarcity and conflicts over meeting demand?
Prior to 2035, world governments, academia, and even private sector labs should have been be utilized to search out the most promising energy sources with the greatest efficiencies that will meet the world’s long term energy needs. The push should be to develop free or extremely low cost energy systems such as fusion or kinetic systems for electricity production, and a hydrogen based fuel source for vehicles. We must begin this researching process and planning for this process now.
