Why are solar and wind energy scarce commodities?

non depletable energy resources

Growth in consumption of coal and oil could end by 2020 due to increased uptake of renewables and natural gas. I think that society should turn to non-depletable resources such as solar energy, wind energy, geothermal energy and hydroelectric energy for our energy needs. Globally, there are an estimated 7. We as a society need to study and fully develop these non-depletable resources. A graph of energy use in the United States up until 1900 shows oil and natural gas with about the same importance in 1900 as wind and solar played in 2010.

Active uses technologies to harness the energy, passive doesn't. In 1885, , commenting on the discovery of the in the solid state, wrote: In conclusion, I would say that however great the scientific importance of this discovery may be, its practical value will be no less obvious when we reflect that the supply of solar energy is both without limit and without cost, and that it will continue to pour down upon us for countless ages after all the coal deposits of the earth have been exhausted and forgotten. Geothermal energy Steam rising from the in Iceland Global geothermal capacity in 2017 was 12. Rotting garbage, and agricultural and human waste, all release methane gas — also called or. It is not just about the direct impact of rising temperatures and changing weather patterns which impact human livelihoods as floods or dry seasons proliferate. It is composed of living materials, which classifies it as a fossil fuel.

Geothermal wells release greenhouse gases trapped deep within the earth, but these emissions are much lower per energy unit than those of fossil fuels. Natural monopolies occur in industries which exhibit decreasing average long-run costs due to size economies of scale. Extremely high temperature and pressure cause some rock to melt, which is commonly known as magma. But the point to make is that by continuing to use non-renewable energy we acknowledge that such disasters are acceptable and even preferable to switching to low carbon and renewable energy sources. Direct geothermal for heating is also growing rapidly.

Azevedo Ramos da Silva 2004. Why turn to the non-depletable energy resources? A non-renewable energy resource can be defined as an energy resource that cannot sustain its consumption rate. Station Country Location Capacity Refs 1. Geothermal power is cost effective, reliable, sustainable, and environmentally friendly, but has historically been limited to areas near boundaries. Couple of nuclear disasters has already occurred in past including Chernobyl and Island Three Miles.

Ethanol can be used as a fuel for vehicles in its pure form, but it is usually used as a to increase octane and improve vehicle emissions. Their excessive extraction and use has resulted in degradation of environment and ecological imbalance. Renewable Energy News and Articles. Unlike most land-based solar plants, floating arrays can be unobtrusive because they are hidden from public view. Only Scotland and Ontario have stopped burning coal, largely due to good natural gas supplies. Imagine a planet so polluted that smog is in the air so bad that one cannot see very far, lakes and streams are poisoned, and land so badly scarred from people trying to find more energy sources.

In the 1970s environmentalists promoted the development of renewable energy both as a replacement for the eventual , as well as for an escape from dependence on oil, and the first electricity generating appeared. It is a major source of fuel that is used in vehicles. High Temperature Geothermal energy is from generated and stored in the Earth. These disasters have again raised several questions on safety of nuclear power plants and people who work in these plants. More powerful models are in development, see. The is the undisputed leader of offshore power with half of the world's installed capacity ahead of Denmark, Germany, and China.

Innovative hybrid systems have emerged between countries and regions. It has reached a point where the word is facing rapid starvation in this sector. China is the largest producer of hydroelectricity in the world and has more than 45,000 small hydro installations. EurLex-2 The criteria aim, in particular, at promoting resource efficiency by fostering recycling of paper, by reducing discharges of toxic or eutrophic substances into waters, by reducing environmental damage or risks related to the use of energy global warming, acidification, ozone depletion , depletion of non-renewable resources through the reduction of energy consumption and related emissions to air and at reducing environmental damage or risks related to the use of hazardous chemicals and applying sustainable management principles in order to safeguard forests. Despite accounting only for 2% of global energy generation, wind power electricity generation is growing rapidly and it has doubled over the past three years and in countries like Denmark it already accounts for 20% of stationary electricity production. It is clear that something needs to change. There are numerous organizations within the academic, federal, and commercial sectors conducting large scale advanced research in the field of renewable energy.

Ocean energy has the potential of providing a substantial amount of new renewable energy around the world. This energy consumption is divided as 8. We are a couple of environmentalists who seek inspiration for life in simple values based on our love for nature. Biodiesel is made from , or recycled greases. However, indirectly solar-charged vehicles are widespread and are available commercially. There are no fuel costs or emissions during operation of the power stations. It's unclear if there are failures with policy or renewable energy, but twenty years after the Kyoto Protocol fossil fuels are still our primary energy source and consumption continues to grow.

Industrial biomass can be grown from numerous types of plants, including , , , , , , , , , and a variety of tree species, ranging from to. At the national level, at least 30 nations around the world already have renewable energy contributing more than 20% of energy supply. Use of biomass for fire did not become commonplace until many hundreds of thousands of years later, sometime between 200,000 and 400,000 years ago. The brutal truth of the matter is that our resources of energy we are using are not going to last forever. We have based our lives on them and other resources like them. Biodiesel is produced from oils or fats using and is the most common biofuel in Europe. Another downside of nuclear energy is that it can be used to make nuclear bomb.

At least 47 nations around the world already have over 50 percent of electricity from renewable resources, with Iceland generating all its electrical power from renewable energy though this does not include non-electrical energy e. As a result, geothermal power has the potential to help mitigate if widely deployed in place of fossil fuels. Biomass can be converted to other usable forms of energy such as gas or transportation fuels such as and. Unfortunately, has seriously eroded public trust in oil companies and has implicated several high ranking Brazilian officials. Global warming is placing a strain on many natural resources such as water. National targets now exist in at least 98 countries.
