An electricity shortage is felt most acutely in heating, cooking, and water supply. Therefore, a sustained energy crisis may become a humanitarian crisis.

If an energy shortage is prolonged a crisis management phase is enforced by authorities. Energy audits may be conducted to monitor usage. Various curfews with the intention of increasing energy conservation may be initiated to reduce consumption.

Wars and attacks do not solve the problem of energy crisis, on the contrary they destroy the potential sources of energy.

There are some downsides of using hydrogen as a fuel :
1.Few filling stations sell hydrogen.
2.Hydrogen must be compressed and liquefied, and then stored in tough, insulated fuel tanks.
3.Atmospheric pollution may be generated during the production of hydrogen.
4.Hydrogen fuel cells do not work at very low temperatures, and they may also require a platinum catalyst (platinum is expensive and prone to contamination by impurities).

Less usage of automobiles and controlling population he following measures can help in controlling hydro carbon pollution
Hence option C is the correct answer.

Hydrogen is both powerful and efficient. It is enough to provide power for powerful machines such as spaceships. Also, it is environmentally friendly and is a much safer choice compared to other fuel sources. Hydrogen is three times as powerful as gasoline and other fossil fuels. This means that it can accomplish more with less.

Renewable sources are a bit costly as compared to fossil fuels but they are eco-friendly.

Energy simulation software can be used by big corporates and corporations to redesign building unit and reduce running business energy cost. Engineers, architects and designers could use this design to come with most energy efficient building and reduce carbon footprint. Hence it cannot be the reason for energy crisis, rather it is the solution to energy crisis.

Both developed and developing countries should adopt a common stand on climate change. They should focus on reducing greenhouse gas emissions through an effective cross border mechanism. With current population growth and over consumption of resources, the consequences of global warming and climate change cannot be ruled out. Both developed and developing countries must focus on emissions cuts to cut their emission levels to half from current levels by 2050.

Tax hikes, strikes, military coup, political events, severe hot summers or cold winters can cause sudden increase in demand of energy and can choke supply. A strike by unions in an oil producing firm can definitely cause an energy crisis. Hence tax hikes are the reason for the increase in energy crisis not the solution.
