Renewable for space heating 2. This oil exists in huge quantities trillions of barrels particularly in Alberta, Canada and Venezuela. It is true oil but in deposits which take special methods to recover the oil. Oil sands must either be mined, or recovered by the SAGD SAG-D process steam assisted gravity drainage in which steam is injected in the upper of two parallel pipes and the oil is collected in the lower pipe.
Further information on power production see: Thorium-based nuclear power Thorium is a fissionable material for possible future use in a thorium-based reactor.
Proponents of thorium reactors claims several potential advantages over a uranium fuel cyclesuch as thorium's greater abundancebetter resistance to nuclear weapons proliferation   and reduced plutonium and actinide production.
The public can buy shares of alternative energy companies from various stock markets, with wildly volatile returns.
The recent IPO of SolarCity demonstrates the nascent nature of this sector- within a few weeks, it already had achieved the second highest market cap within the alternative energy sector.
Alternative energy sources which are renewable and have lower carbon emissions than fossil fuels are hydropower, wind energy, solar energy, geothermal energy, and bio fuels.
Each of these four segments involve very different technologies and investment concerns. For example, photovoltaic solar energy is based on semiconductor processing and accordingly, benefits from steep cost reductions similar to those realized in the microprocessor industry i.
PV solar energy is perhaps the only energy technology whose electricity generation cost could be reduced by half or more over the next five years. Better and more efficient manufacturing process and new technology such as advanced thin film solar cell is a good example of that helps to reduce industry cost.
In contrast, because wind power has been harnessed for over years, its underlying technology is relatively stable.
Its economics are largely determined by siting e. Because current wind turbines are often in excess of meters high, logistics and a global manufacturing platform are major sources of competitive advantage.
These issues and others were explored in a research report by Sanford Bernstein.
In response, many smaller companies have rapidly increased research and development into radically different ways of powering consumer vehicles. Hybrid and battery electric vehicles are commercially available and are gaining wider industry and consumer acceptance worldwide.
|What are the main substitutes for oil and gas energy? | Investopedia||Its energy is found in fossil fuels as well as all living things. There is a great deal of information and enthusiasm today about the development and increased production of our global energy needs from alternative energy sources.|

First there must be increased understanding of how alternative energies are beneficial; secondly the availability components for these systems must increase; and lastly the pay-back period must be decreased.
The continue adoption of these vehicles depend on investment in public charging infrastructure, as well as implementing much more alternative energy for future transportation.
This research spans several areas of focus across the alternative energy spectrum.
Most of the research is targeted at improving efficiency and increasing overall energy yields. Additionally, their use also dispenses with the trade-off that has existed between environmental conservation and economic growth.
Mechanical energy[ edit ] Mechanical energy associated with human activities such as blood circulation, respiration, walking, typing and running, is ubiquitous but usually wasted.
It has attracted tremendous attention from researchers around the globe to find methods to scavenge such mechanical energies. The best solution currently is to use piezoelectric materials, which can generate flow of electrons when deformed. Various devices using piezoelectric materials have been built to scavenge mechanical energy.
Considering that the piezoelectric constant of the material plays a critical role in the overall performance of a piezoelectric device, one critical research direction to improve device efficiency is to find new material of large piezoelectric response.
Lead Magnesium Niobate-Lead Titanate PMN-PT is a next-generation piezoelectric material with super high piezoelectric constant when ideal composition and orientation are obtained.
InPMN-PT Nanowires with a very high piezoelectric constant were fabricated by a hydro-thermal approach  and then assembled into an energy-harvesting device . The record-high piezoelectric constant was further improved by the fabrication of a single-crystal PMN-PT nanobelt,  which was then used as the essential building block for a piezoelectric nanogenerator.Sep 06, · The oil, coal and natural gas companies know these are serious problems.
But until our renewable energy sources become more viable as major energy providers, the only alternative for our global population is for these companies to continue tapping into the fossil fuel reserves to meet our energy needs.
Alternative energy is any energy source that is an alternative to fossil urbanagricultureinitiative.com alternatives are intended to address concerns about fossil fuels, such as its high carbon dioxide emissions, an important factor in global warming.
Marine energy, hydroelectric, wind, geothermal and solar power are all alternative sources of energy.. The nature of what constitutes an alternative energy source. The main substitutes for oil and gas energy include nuclear power, solar power, ethanol and wind power.
Fossil fuels still dwarf these alternatives in global and domestic energy markets, but there. The National Academies, advisers to the nation on science, engineering, and medicine, provides objective information about the United States' current energy sources and uses, as well as a look forward to the future of energy.
Although the major oil companies have stepped back from their earlier support of renewable fuels, they have endorsed and invested in some major players with most of the major oil companies investing in renewable energy projects. One can classify energy into: non-renewable energy (oil, natural gas, coal, uranium -- all with finite lifetimes); and renewable energy (hydroelectric, biomass, geothermal, wind and solar).
On the scale of human civilization, fusion can also be considered as renewable.
