Five Predictions For The Future Of Energy

There seems to be new predictions about how renewable energy will be used in the coming decades. Do you use all solar energy in two years? Five o'clock? Do you use more nuclear power? Experts like to make predictions. Here we summarize some of the most exciting (and irritated) forecasts of the last few months. We do not have crystal balls to say that these are ultimately correct, but with many choices, some people look like genius.

The Institute of Electrical and Electronics Engineers (IEEE) said. According to this organization, the photovoltaic power generation system can become the most economical electric form within 10 years. However, it is limited to cases where the solar cell industry rapidly improves the efficiency of solar cells and continues to produce economies of scale. "Generation cost as solar power generation

According to Reuters, natural gas generated by Cher will lose economic benefits of renewable energy over the next few years. As the price of the sun and the wind continue to decline, natural gas will remain at the forefront. Even if the cost of offshore wind power generation was the same as the cost of natural gas by 2015 (as predicted by the German utility E.ON), when the wind is not blowing, make a backup power supply Additional cost is required for. As long as the price is cheap, utilities can choose to permanently use fossil fuels instead of intermittent renewable energy.

Good news: The International Energy Association believes that renewable energy will grow from 8% of total energy consumption in 2009 to 13% in 2035. Bad news: Coal and natural gas will also grow - coal power generation will increase by 25% from 2009 to 2035, shale gas production will increase nearly 4 times in the same period. This is very important to reduce carbon emissions

Of course, this is unlikely, but the research team at Stanford University believes that it is necessary to use renewable energy by 2030 in all new energy production plants and to convert existing plants by 2050 It is. Energy moves the planet. - In bad forecasts, 90% of energy production comes from wind and solar, the remaining 10% comes from hydropower, geothermal, wave / tidal energy. For vehicles, trains, ships, and other means of transport, hydrogen-powered fuel cells using hydrogen fuel are used. The only problem is to defeat the fossil fuel industry to where it does not exist. This is the best dream - but we should be enthusiastic at least for this dream. Please come back in 2050

The future of coal as an energy source is not known, but there are many predictions on how to implement coal. In countries where crude oil prices are rising, coal may become a cheaper energy source. Over the next 20 years, total energy consumption of major coal will remain about the same, and it is expected to gradually increase thereafter. There are several problems with coal cleanliness, which leads to a lot of pollution, but by dealing with burning fumes these problems can be solved. However, coal is still an important producer of carbon dioxide and most countries are trying to reduce greenhouse gas emissions, so it may hurt plans to use it as an alternative energy source.

Looking at the past, present and forecast of future greenhouse gas emissions, you can see two things: greenhouse gas emissions (rises) and total emissions concentrations (rises). Because of pattern matching heuristics, most people think that reducing emissions will also reduce total emissions, but this is incorrect as the greenhouse effect is cumulative. As the greenhouse gas emissions increase each year, its influence will become stronger. Just like putting water in a bathtub, you need to take something out of the system to lower the level; just lowering the addition rate can not prevent water / temperature rise. In this case, the key to better understanding the future is to take the composition of the chart into account to more accurately convey the dynamics of the climate system. In this example, plotting the net removal as a negative value (like a climate system) and adding "net emissions" will solve the problem.

The energy meter can easily measure the output of the solar system and directly quantify its impact. Regarding predictions, organizations like ASHRAE seems to be solar system design and performance tools like PV Syst, Folsom Labs, and now the Google Project Sunroof to provide high-accuracy estimated savings for future energy We provide rich historical climate data. Solar energy does not require changes in employee or customer behavior and does not require aesthetic changes inside the building to save cost. By allowing companies to operate the business as usual, we can utilize solar energy without sacrificing productivity.
