Specialty Definition: Renewable energy

(From Wikipedia, the free Encyclopedia)

Renewable energy is energy from a source which is not subject to depletion in a human timescale such as the Sun's rays, wind, waves, rivers, tides and the heat from radioactive decay in the Earth's core as well as biomass. Renewable energy does not include energy sources which are dependent upon limited resources, such as fossil fuels and nuclear fission power (collectively known as nuclear-fossil fuels).

Renewable energy may be used directly (as in solar ovens, geothermal heat pumps, and windmills) or be used to generate electricity or create fuels such as ethanol. Throughout human existence, wood has been critically important as a thermal energy source. Historically, only the power of falling water in rivers (hydroelectricity) has been significantly tapped for the generation of electricity. However, recent years have seen the rapid development of wind generation farms by mainstream power companies. Solar energy's main human application has been in agriculture and forestry, via photosynthesis, but increasingly it is harnessed for heat and electricity. Geothermal power can be used to generate electricity near hot spots in the Earth's crust. Agriculturally produced biomass fuels, such as biodiesel, ethanol and bagasse (a byproduct of sugar cane cultivation) are burned in internal combustion engines or boilers.

Around 80% of our energy requirements are focused around heating or cooling our buildings and powering the vehicles that ensure our mobility (cars, trains, airplanes). This is the core of our energy problem and the domain where solar architecture, high energy productivity and a new way of energy awareness is required.

Still most technical discussions will focus on the remaining 20% - renewable energy sources for electricity production, because it is the area with one the biggest pending economic conflicts.

The first US politician with a "solar vision" was Jimmy Carter. He understood the long term consequences of the 1973 energy crisis.

Pros and cons

Renewable energy sources are fundamentally different from fossil fuel or nuclear power plants because of their widespread occurrence and abundance - the sun will 'power' these 'powerplants' for the next 4 billion years. Some renewable sources do not emit any additional carbon dioxide and do not introduce any new risks - like nuclear waste.

Since they are harnessing relatively low-intensity energy this new kind of power plant needs to be distributed over a large area. To put the phrases 'low-intensity' and 'large area' easier to understand one should image that in order to produce 1000 kWh of electricity - a typical per-month-per-capita consumption of electricity in Western countries - a house owner in cloudy Europe needs to cover 10 square meters of roof with solar panels.

The disadvantage of renewables is their impact on local environments and their visibility to everybody. Some people dislike the aesthetics of wind turbines or bring up nature conservation issues when it comes to large solar-electric installations outside of cities. However, it is up to the imagination of the people to utilize these renewable technologies in an efficient and aesthetically pleasing way: fixed solar collectors can double as noise barriers along highways, roof-tops are available already and could even be replaced totally by solar collectors, etc.

Moreover, it is important to realize that any environmental impact (space consumption, noise emission, etc) can be solved by the local people who are affected. It is also important that the impact of the major production of energy by non-renewable fuels is addressed to minimise nuclear waste, global warming.

The second difficulty is the variable and diffuse nature of renewable energies (with the exception being geothermal energy, which is however only accessible where the earth's crust is thin, such as near hot springs and natural geysers). For electricity this means that either there must be reliable overlapping sources or some means of storage on a reasonable scale (pumped-storage hydro systemss, batteries, future hydrogen fuel cells, etc.). So, because of the currently expensive energy storage a stand-alone system is only economic in rare cases.

If renewable and distributed generation were to become widespread, electric power transmission and electricity distribution systems would no longer be the main distributors of electrical energy but would operate to balance the electricity needs of local communities. Those with surplus energy would sell to areas needing "top ups".

Sources of renewable energy

There are several types of renewable energy, most are mentioned below:

Solar power.
Wind power.
Geothermal energy.
Electrokinetic energy.
Hydroelectricity.
Biomatter, including Biogas Energy.

Of course there are some small scale applications as well.

Piezo electric crystals embedded in the sole of a shoe can yield a small amount of energy with each step. Vibration from engines can stimulate piezo electric crystals.
Some watches are already powered by movement of the arm.
Special antennae can collect energy from stray radiowaves or even light (EM radiation).

Most renewable energy sources can trace their roots to solar energy, with the exception of geothermal and tidal wave power. For example, wind is caused by the sun heating the earth unevenly. Hot air is less dense, so it rises, causing cooler air to move in to replace it. Hydroelectric power can be ultimately traced to the sun too. When the sun evaporates water in the ocean, the vapor forms clouds which later fall on mountains as rain which is routed through turbines to generate electrity. The transformation goes from solar energy to potential energy to kinetic energy to electric energy.

Some people want to put Nuclear energy into the renewable category by stressing that it is not contributing to global warming. However, the fact that it uses a depleting resource (uranium) means that it cannot be included in such a classification.

Solar Energy

Since most renewable energy is "Solar Energy" this term is slightly confusing and used in two different ways: firstly as a synonym for "renewable energies" as a whole (like in the slogan "Solar not nuclear") and secondly for the energy that is directly collected from solar radiation. In this section it is used in the latter category.

There are actually two separate approaches to solar energy, termed active solar and passive solar. The elements outlined below are included in active solar.

Electrical energy

However, for electricity generation ground based solar power has limited potential, as it is too diffuse and too intermittent. First, ground based solar input is interrupted by night and by cloud cover, which means that solar electric generation inevitably has a low capacity factor, typically less than 20%. Also, there is a low intensity of incoming radiation, and converting this to high grade electricity is still relatively inefficient (14% - 18%), though increased efficiency or lower production costs have been the subject of much research over several decades.

Two methods of converting the Sun's radiant energy to electricity are the focus of attention. The better known method uses sunlight acting on photovoltaic (PV) cells to produce electricity. This has many applications in satellites, small devices and lights, grid-free applications, earthbound signalling and communication equipment, such as remote area telecommunications equipment. Sales of solar PV modules are increasing strongly as their efficiency increases and price diminishes. But the high cost per unit of electricity still rules out most uses.

Several experimental PV power plants mostly of 300 - 500 kW capacity are connected to electricity grids in Europe and the USA. Japan has 150 MWe installed. A large solar PV plant was planned for Crete. In 2001 the world total for PV electricity was less than 1000 MWe with Japan as the world's leading producer. Research continues into ways to make the actual solar collecting cells less expensive and more efficient. Other major research is investigating economic ways to store the energy which is collected from the Sun's rays during the day.

The second method for utilizing solar energy is solar thermal. A solar thermal power plant has a system of mirrors to concentrate the sunlight on to an absorber, the resulting heat then being used to drive turbines. The concentrator is usually a long parabolic mirror trough oriented north-south, which tilts, tracking the Sun's path through the day. A black absorber tube is located at the focal point and converts the solar radiation to heat (about 400°C) which is transferred into a fluid such as synthetic oil. The oil can be used to heat buildings or water, or it can be used to drive a conventional turbine and generator. Several such installations in modules of 80 MW are now operating. Each module requires about 50 hectares of land and needs very precise engineering and control. These plants are supplemented by a gas-fired boiler which ensures full-time energy output. The gas generates about a quarter of the overall power output and keeps the system warm overnight. Over 800 MWe capacity worldwide has supplied about 80% of the total solar electricity to the mid-1990s.

Alternatively, many individuals have installed small-scale PV arrays for domestic consumption. Some, particularly in isolated areas, are totally disconnected from the main power grid, and rely on a surplus of generation capacity combined with batteries and/or a fossil fuel generator to cover periods when the cells are not operating. Others in more settled areas remain connected to the grid, using the grid to obtain electricity when solar cells are not providing power, and selling their surplus back to the grid. This works reasonably well in many climates, as the peak time for energy consumption is on hot, sunny days where air conditioners are running and solar cells produce their maximum power output. Many U.S. states have passed "net metering" laws, requiring electrical utilities to buy the locally-generated electricity for price comparable to that sold to the household. Photovoltaic generation is still considerably more expensive for the consumer than grid electricity unless the usage site is sufficiently isolated, in which case photovoltaics become the less expensive.

A simple proposal for a solar electrical plant is the solar tower, in which a large area of land would be covered by a greenhouse made of something as simple as transparent foil, with a tall lightweight tower in the centre, which could also be composed largely of foil. The heated air would rush to and up the centre tower, spinning a turbine. A system of water pipes placed throughout the greenhouse would allow the capture of excess thermal energy, to be released throughout the night and thus providing 24-hour power production. A 200 MWe tower is proposed near Mildura, Australia.

Thermal energy

The main role of solar energy in the future may be that of direct heating. Much of our energy need is for heat below 60°C (140°F) - e.g. in hot water systems. A lot more, particularly in industry, is for heat in the range 60 - 110°C. Together these may account for a significant proportion of primary energy use in industrialised nations. The first need can readily be supplied by solar power much of the time in some places, and the second application commercially is probably not far off. Such uses will diminish to some extent both the demand for electricity and the consumption of fossil fuels, particularly if coupled with energy conservation measures such as insulation.

Domestic solar hot water systems are common in the hotter areas of Australia, and simply consist of a network of dark-coloured pipes running beneath a window of heat-trapping glass. They typically have a backup electric or gas heating unit for cloudy days. Such systems can actually be justified purely on economic grounds, particularly in some remoter areas of Australia where electricity is expensive.

With adequate insulation, heat pumps utilising the conventional refrigeration cycle can be used to warm and cool buildings, with very little energy input other than energy needed to run a compressor. Eventually, up to ten percent of the total primary energy need in industrialised countries may be supplied by direct solar thermal techniques, and to some extent this will substitute for base-load electrical energy.

Large scale solar thermal powerplants, as mentioned before, can be used to heat buildings, but on a smaller scale solar ovens can be used on sunny days. Such an oven or solar furnace uses mirrors or a large lens to foccuss the Sun's rays onto a baking tray or black pot which heats up as it would in a standard oven.

Solar towers would also use thermal energy.

Wind Energy

Wind turbines have been used for household electricity generation in conjunction with battery storage over many decades in remote areas. Generator units of more than 1 MWe are now functioning in several countries. The power output is a function of the cube of the wind speed, so such turbines require a wind in the range 3 to 25 metres/second (11 - 90 km/hr), and in practice relatively few land areas have significant prevailing winds. Like solar, wind power requires alternative power sources to cope with calmer periods.

There are now many thousands of wind turbines operating in various parts of the world, with a total capacity of over 31,000 MWe of which Europe accounts for 75% (ultimo 2002). Germany is the leading producer of wind generated electricity with over 8000 MWe in 2001. In 2002 the U.S.A. produced over 4,200 Mwe of wind energy, second only to Germany. New (offshore) wind parks are being planned and built all over the world. This has been the most rapidly-growing means of electricity generation at the turn of the 21st century and provides a valuable complement to large-scale base-load power stations. Denmark generates over 10% of its electricity with windturbines, whereas windturbines account for 0.4% of the total electricity production on a global scale (ultimo 2002). The most economical and practical size of commercial wind turbines seems to be around 600 kWe to 1 MWe, grouped into wind farms up to 6 MWe. Most turbines operate at about 25% load factor over the course of a year, but some reach 35%.

Geothermal Energy

Where hot underground steam or water can be tapped and brought to the surface it may be used to generate electricity. Such geothermal power sources have potential in certain parts of the world such as New Zealand, USA, Philippines and Italy. Some 8000 MWe of capacity is operating. There are also prospects in certain other areas for pumping water underground to very hot regions of the Earth's crust and using the steam thus produced for electricity generation. An Australian startup company, Geodynamics, proposes to build a commercial plant in the Cooper Basin region of South Australia using this technology by 2004.

Electrokinetic energy

It harnesses what happens to water when it is pumped through tiny channels.

For more information see electrokinetics (water).

Hydroelectric Energy

Hydroelectric energy is cleaner than burning fossil fuels or gas which produce CO2.

Biomatter & Biogas Energy

Biomatter or biomass can be used to produce biofuel ( bioalcohols -like methanol and ethanol- and biodiesel). Biodiesel can be used in modern diesel vehicles and can be obtained from waste and crude vegetable and animal oil and fats (lipids).

All sorts of biomatter can be burnt to heat water and to drive turbines. Plants partly use photosynthesis to store solar energy, water and CO₂. Sugar cane residue, wheat chaff, corn cobs and other plant matter can be, and is, burnt quite successfully. The process releases no net CO₂. Of course electricity is not the only form of practical energy. In some areas corn, sugarbeets, cane and grasses are grown specifically to produce ethanol (also known as alcohol) a liquid which can be used in internal combustion engines and fuel cells.

Animal feces release methane under the influence of anaerobic bacteria which can also be used to generate electricity. See biogas.

Renewable energy needs a reliable and efficient storage system

Sun, wind, tides and waves cannot be controlled to provide directly either continuous base-load power, or peak-load power when it is needed. In practical terms, without proper energy storage methods they are therefore limited to some 20% of the capacity of an electricity grid, and cannot directly be applied as economic substitutes for fossil fuels or nuclear power, however important they may become in particular areas with favourable conditions. Nevertheless, such technologies are the only choice for the world's energy future, even if they are unsuitable for carrying the main burden of supply at this time. If there were some way that large amounts of electricity from intermittent producers such as solar and wind could be stored efficiently, the contribution of these technologies to supplying base-load energy demand would be much greater. Already in some places pumped storage is used to even out the daily generating load by pumping water to a high storage dam during off-peak hours and weekends, using the excess base-load capacity from coal or nuclear sources. During peak hours this water can be used for hydroelectric generation.

Relatively few places have scope for pumped storage dams close to where the power is needed, and overall efficiency is low. Means of storing large amounts of electricity as such in giant batteries or by other means have not yet been put to general use, because of the missing business case - but one possible technologies already exist: large scale flow batteries. A long term vision are hydrogen fuel cells for energy storage.

There is some scope for reversing the whole way we look at power supply, in its 24-hour, 7-day cycle, using peak load equipment simply to meet the daily peaks. Today's peak-load equipment could be used to some extent to provide infill capacity in a system relying heavily on renewables. The peak capacity would complement large-scale solar thermal and wind generation, providing power when they were unable to. Improved ability to predict the intermittent availability of wind enables better use of this resource. In Germany it is now possible to predict wind generation output with 90% certainty 24 hours ahead. This means that it is possible to deploy other plants more effectively so that the economic value of that wind contribution is greatly increased.

Hydrogen fuel cells

Hydrogen is widely seen as a possible fuel for hydrogen cars, if certain problems can be overcome economically. It may be used in conventional internal combustion engines, or in fuel cells which convert chemical energy directly to electricity without flames, in the same way the human body burns fuel. Making hydrogen requires either reforming natural gas (methane) with steam, or, for a renewable and more ecologic source, the electrolysis of water into hydrogen and oxygen. The former process has carbon dioxide as a by-product, which exacerbates (or at least does not improve) greenhouse gas emissions relative to present technology. With electrolysis, the greenhouse burden depends on the source of the power, and both intermittent renewables and nuclear energy are considered here.

With intermittent renewables such as solar and wind, matching the output to grid demand is very difficult, and beyond about 20% of the total supply, apparently impossible. But if these sources are used for electricity to make hydrogen, then they can be utilised fully whenever they are available, opportunistically. Broadly speaking it does not matter when they cut in or out, the hydrogen is simply stored and used as required.

A quite different rationale applies to using nuclear energy for hydrogen. Here the plant would be run continuously at full capacity, with perhaps all the output being supplied to the grid in peak periods and any not needed to meet civil demand being used to make hydrogen at other times. This would mean maximum efficiency for the nuclear power plants and that hydrogen was made opportunistically when it suited the grid manager.

About 50 KWh (1/144,000 J) is required to produce a kilogram of hydrogen by electrolysis, so the cost of the electricity clearly is crucial.

Countries that use renewable energy

Iceland is a world leader in renewable energy due to its abundant hydro and geothermal energy sources. Over 99% of the country's electricity is from renewable sources and most of its urban household heating is geothermal. Israel is also notable as much of its household hot water is heated by solar means. These countries' successes are at least partly based on their geographical advantages. The United States is the leading producer of hydroelectric power and geothermal electrical energy.
