The Great Renewable Energy Con explained by Dr Benny Peiser

Consistent renewable energy -

Heat is extracted from geothermal reservoirs using wells or other means. Reservoirs that are naturally sufficiently hot and permeable are called hydrothermal reservoirs, whereas reservoirs that are sufficiently hot but that are improved with hydraulic stimulation are called enhanced geothermal systems.

Once at the surface, fluids of various temperatures can be used to generate electricity. The technology for electricity generation from hydrothermal reservoirs is mature and reliable, and has been operating for more than years.

Hydropower harnesses the energy of water moving from higher to lower elevations. It can be generated from reservoirs and rivers.

Reservoir hydropower plants rely on stored water in a reservoir, while run-of-river hydropower plants harness energy from the available flow of the river. Hydropower reservoirs often have multiple uses - providing drinking water, water for irrigation, flood and drought control, navigation services, as well as energy supply.

Hydropower currently is the largest source of renewable energy in the electricity sector. It relies on generally stable rainfall patterns, and can be negatively impacted by climate-induced droughts or changes to ecosystems which impact rainfall patterns.

The infrastructure needed to create hydropower can also impact on ecosystems in adverse ways. For this reason, many consider small-scale hydro a more environmentally-friendly option , and especially suitable for communities in remote locations. Ocean energy derives from technologies that use the kinetic and thermal energy of seawater - waves or currents for instance - to produce electricity or heat.

Ocean energy systems are still at an early stage of development, with a number of prototype wave and tidal current devices being explored. The theoretical potential for ocean energy easily exceeds present human energy requirements. Bioenergy is produced from a variety of organic materials, called biomass, such as wood, charcoal, dung and other manures for heat and power production, and agricultural crops for liquid biofuels.

Most biomass is used in rural areas for cooking, lighting and space heating, generally by poorer populations in developing countries. Modern biomass systems include dedicated crops or trees, residues from agriculture and forestry, and various organic waste streams. Energy created by burning biomass creates greenhouse gas emissions, but at lower levels than burning fossil fuels like coal, oil or gas.

However, bioenergy should only be used in limited applications, given potential negative environmental impacts related to large-scale increases in forest and bioenergy plantations, and resulting deforestation and land-use change. International Energy Agency Renewables.

Nonrenewable sources of energy are only available in limited amounts. Nonrenewable energy sources are also typically found in specific parts of the world, making them more plentiful in some nations than others.

By contrast, every country has access to sunshine and wind. Many nonrenewable energy sources can endanger the environment or human health. To top it off, all of these activities contribute to global warming.

Humans have been harnessing solar energy for thousands of years—to grow crops, stay warm, and dry foods. Solar, or photovoltaic PV , cells are made from silicon or other materials that transform sunlight directly into electricity.

Distributed solar systems generate electricity locally for homes and businesses, either through rooftop panels or community projects that power entire neighborhoods. Solar farms can generate enough power for thousands of homes, using mirrors to concentrate sunlight across acres of solar cells.

Solar supplies nearly 3 percent of U. electricity generation some sources estimate it will reach nearly 4 percent in But 46 percent of all new generating capacity came from solar in Today, turbines as tall as skyscrapers—with turbines nearly as wide in diameter—stand at attention around the world.

Wind, which accounts for 9. electricity generation , has become one of the cheapest energy sources in the country. Top wind power states include California, Iowa, Kansas, Oklahoma, and Texas, though turbines can be placed anywhere with high wind speeds—such as hilltops and open plains—or even offshore in open water.

Hydropower is the largest renewable energy source for electricity in the United States, though wind energy is soon expected to take over the lead.

Nationally and internationally , large hydroelectric plants—or mega-dams —are often considered to be nonrenewable energy. Mega-dams divert and reduce natural flows, restricting access for animal and human populations that rely on those rivers. Small hydroelectric plants an installed capacity below about 40 megawatts , carefully managed, do not tend to cause as much environmental damage, as they divert only a fraction of the flow.

Biomass is organic material that comes from plants and animals, and includes crops, waste wood, and trees. When biomass is burned, the chemical energy is released as heat and can generate electricity with a steam turbine.

Biomass is often mistakenly described as a clean, renewable fuel and a greener alternative to coal and other fossil fuels for producing electricity.

However, recent science shows that many forms of biomass—especially from forests—produce higher carbon emissions than fossil fuels. There are also negative consequences for biodiversity.

Still, some forms of biomass energy could serve as a low-carbon option under the right circumstances. For example, sawdust and chips from sawmills that would otherwise quickly decompose and release carbon can be a low-carbon energy source.

Drilling deep wells brings very hot underground water to the surface as a hydrothermal resource, which is then pumped through a turbine to create electricity. Geothermal plants typically have low emissions if they pump the steam and water they use back into the reservoir.

There are ways to create geothermal plants where there are not underground reservoirs, but there are concerns that they may increase the risk of an earthquake in areas already considered geological hot spots.

Some tidal energy approaches may harm wildlife, such as tidal barrages, which work much like dams and are located in an ocean bay or lagoon.

Passive solar homes are designed to welcome in the sun through south-facing windows and then retain the warmth through concrete, bricks, tiles, and other materials that store heat. Ideally, this energy should also cause minimal damage to the environment. Several energy sources can do this job, but which one is the most reliable?

Currently, nuclear power is the most reliable. Unfortunately, renewable energy sources are still the most unreliable, especially on a local scale. This is because the efficiency of renewable energy sources depends heavily on their location.

For example, solar panels in Arizona will generate a lot of electricity, while those installed in Alaska will be far less productive. The same goes for wind power: Oklahoma is the third-largest producer of wind power, while Mississippi, the least windy state, will have a much harder time.

One benefit of wind power is that we can harness it in places where there are no people or even land. This simply comes down to how easy it is to produce the energy, and then how easy it is to store.

For example, coal is difficult to extract but easy to store. We have to mine into the earth, which is extremely dangerous. For example, on October 27, , a man died in a coal mine in Pennsylvania, and just over ten days before, two men died in Kentucky within a week. However, once the coal has been extracted, it is easily stored for long periods of time.

On the other hand, solar power is easy to find no dangerous mining here! but difficult to store because it requires a lot of battery power. The good news is this is something scientists and companies like Tesla are working on all the time. Renewable energy sources are inherently better for the planet.

They reduce our reliance on fossil fuels, which release carbon dioxide and methane into the atmosphere and contribute to air pollution and global warming. Think about the size of the batteries you need in your TV remote, and then imagine the size you would need to cover the fluctuations in power needs and the weather for an entire country.

More wind farms, solar farms, and hydropower plants would help build the infrastructure we need. Technology will improve the efficiency of battery storage, solar panels, and wind turbines in the future. Solar power currently provides around 1. Yes , because it will always be available.

As long as humans live on this planet, the sun will always shine, the wind will always blow, and water will always flow. For example, coal mines are vulnerable to earthquakes just as geothermal plants are, and nonrenewable sources also require a lot of infrastructure and power to extract.

A combination of renewable and nonrenewable resources are currently being used to meet our needs, but the time will come, generations from now, when fossil fuels run out and renewable energy sources will have to take their place. Fortunately, many of these are clean energy sources, which will help fight global warming and the air pollution that puts many who live in urban areas at risk of respiratory problems and diseases.

The future of energy may sound strange, confusing, and even concerning, but the good news is that renewable, clean energy sources are growing fast. More governments, scientists, and companies are focused on creating the necessary infrastructure and technology so we can rely more heavily on them in the coming years.

The previous Consisetnt was also criticized enerhy relying too much on storing excess rrnewable Consistent renewable energy water, eenrgy and enerby rocks. The solutions in the current paper address these criticisms by suggesting several different solutions for stabilizing energy produced with percent clean, renewable sources, including solutions with no added hydropower turbines and no storage in water, ice or rocks.

At the heart of this study is the need to match energy supplied by wind, water and solar power and storage with what the researchers predict demand to be in To do this, they grouped countries — for which they created energy roadmaps in a previous study — into 20 regions based on geographic proximity and some geopolitical concerns.

Unlike the previous country study, which matched energy supply with annual-average demand, the present study matches supply and demand in second increments for 5 years to account for the variability in wind and solar power as well as the variability in demand over hours and seasons.

For the study, the researchers relied on two computational modeling programs. The first program predicted global weather patterns from to From this, they further predicted the amount of energy that could be produced from weather-related energy sources like onshore and offshore wind turbines, solar photovoltaics on rooftops and in power plants, concentrated solar power plants and solar thermal plants over time.

The group then combined data from the first model with a second model that incorporated energy produced by more stable sources of electricity, like geothermal power plants, tidal and wave devices, and hydroelectric power plants, and of heat, like geothermal reservoirs.

The second model also included ways of storing energy when there was excess, such as in electricity, heat, cold and hydrogen storage. Further, the model included predictions of energy demand over time.

With the two models, the group was able to predict both how much energy could be produced through more variable sources of energy, and how well other sources could balance out the fluctuating energy to meet demands. Scenarios based on the modeling data avoided blackouts at low cost in all 20 world regions for all five years examined and under three different storage scenarios.

One scenario includes heat pumps — which are used in place of combustion-based heaters and coolers — but no hot or cold energy storage; two add no hydropower turbines to existing hydropower dams; and one has no battery storage.

The fact that no blackouts occurred under three different scenarios suggests that many possible solutions to grid stability with percent wind, water and solar power are possible, a conclusion that contradicts previous claims that the grid cannot stay stable with such high penetrations of just renewables.

Overall, the researchers found that the cost per unit of energy — including the cost in terms of health, climate and energy — in every scenario was about one quarter what it would be if the world continues on its current energy path.

This is largely due to eliminating the health and climate costs of fossil fuels. Also, by reducing water vapor, the wind turbines included in the roadmaps would offset about 3 percent of global warming to date.

Although the cost of producing a unit of energy is similar in the roadmap scenarios and the non-intervention scenario, the researchers found that the roadmaps roughly cut in half the amount of energy needed in the system. So, consumers would actually pay less.

The vast amount of these energy savings come from avoiding the energy needed to mine, transport and refine fossil fuels, converting from combustion to direct electricity, and using heat pumps instead of conventional heaters and air conditioners.

Jacobson and his colleagues said that a remaining challenge of implementing their roadmaps is that they require coordination across political boundaries. In light of this geopolitical complication, they are also working on smaller roadmaps to help individual towns, many of which have already committed to achieving percent renewable energy.

Producing renewable energy is good for the environment, the economy and for people. icon Inexhaustible Renewable resources are always available in nature.

icon Respect for the environment Producing energy from renewable resources drastically reduces CO 2 emissions. icon Versatile Thanks to various technologies, renewable energy can be produced virtually everywhere in the world. icon In constant evolution Technological innovation makes renewable energy production increasingly more efficient.

icon Affordable Large scale renewable energy production is increasingly affordable. It is widely accepted that renewable energy sources are the way forward for a sustainable future. Some days are windier or sunnier than others, and the highs and lows create inconsistency that make renewables less reliable as power sources than fossil fuels.

But the future is bright and there are constantly evolving ideas and technologies to combat the problem. To balance this, renewables work in concert with conventional energies to fill the gaps and create a consistent supply.

Quite counterproductive to the goal of green power supply. An oversupply of energy when there is nowhere for it to be used or stored can mean energy is created and then wasted, or worse, it can cause failures in the gird. One of the ways these issues are being addressed is by exporting excess energy when it is created.
