Non-conventional energy sources for the future energy crises
The subject of non-conventional energy sources will be discussed in this post. Energy is the top priority throughout the world. This is mainly because nations rely primarily on fossil fuel energy sources, whose resources are depleted because of overuse. The other common source that has a safety risk is nuclear power. The quest for other sources of energy is evidently very progressive, in particular for non-conventional energy sources. These technologies offer the benefit of reducing air pollution and also reducing the impacts of global warming on mother earth.
Introduction to Non-conventional energy sources
The stock of fossil fuel is worldwide decreased, as a result of heavy consumption. As a consequence, the focus on non-conventional energy sources has shown promising outcomes. Non-conventional energy sources is now recognised as an alternative for conventional fossil fuel energy. Different sources can be used to produce energy in the non-conventional sector. Wind, solar, wave, water and more are would be included. However, the question is whether these technologies can meet the future energy demand. In order to obtain an answer to this response, detailed studies should be carried out.
Why is renewable energy beneficial to combating climate change?
According to a recent report published by the Intergovernmental Panel on Climate Change (IPCC), non-conventional energy sources can keep greenhouse gas levels below 450 parts per million (PPM) if all available technologies are used to their full potential. As far as climate change is concerned, this level is considered to be the safe level. If it drops below this level, the changes will be unpredictable and could result in disasters.
Conventional energy resources have their drawbacks.
The world’s current energy needs are primarily met by fossil fuels and nuclear power. Both have their own set of limitations. Fossil fuels are limited and contribute to pollution in the atmosphere. To a large extent, air pollution is caused by the amount of polluting gases emitted by motor vehicles and thermal plants. Nuclear power plant safety has yet to be proven.
Non-conventional energy sources: A report by the Intergovernmental Panel on Climate Change (IPCC)
Non-conventional sources, unlike fossil fuels, are renewable. In most countries, electricity production from these sources has already begun and is progressing. According to the IPCC report, 140 GW out of the 300 GW of electricity produced in 2008–09 came from solar and wind sources. The main issue in switching to these sources of production is not the availability of sources, but the cost of production. According to the IPCC report, investment in non-conventional energy sources would be about $5 trillion (trillion = millions of million) dollars over the next decade, with the target of providing enough energy to maintain greenhouse gas emissions below 450 parts per million. During the next decade (2021– 2030), investment for the same number will be seven trillion dollars.
Agenda of the Weather and Climate change conference
The IPCC report will be discussed in depth at the following weather meeting, which is held in South Africa in December 2011. The conference’s overall aim was to re-energize the global alliance for sustainable growth, which was initiated at the Rio Earth Summit 20 years ago. A broad variety of issues relating to long-term sustainability were addressed. The study emphasises the need for a transition to this sustainable, non-conventional energy source, and the IPCC is requesting that every country make this transition. It also seeks to assist developed countries, whose inhabitants, totalling about 2000 million, are currently denied access to energy benefits.
According to projections, electricity generated from non-conventional sources would need to be increased by a factor of twenty by 2050, which would be more than that derived by nuclear sources. Wind and solar have been listed as the primary non-conventional energy sources for the future. The amount that could be extracted by other sources is much smaller. There are also resource constraints in the case of hydroelectric power generation.
