The OPEC oil embargo was an event where the 12 countries that made up OPEC stopped selling oil to the United States. The embargo sent gas prices through the roof. Between 1973-1974, prices more than quadrupled. The embargo contributed to stagflation.

The embargo caused the United States and western European countries to reassess their dependence upon Middle Eastern oil. It also led to far-reaching changes in domestic energy policy, including increased domestic oil production in the United States and a greater emphasis on improving energy efficiency.

The onset of the embargo contributed to an upward spiral in oil prices with global implications. The price of oil per barrel first doubled, then quadrupled, imposing skyrocketing costs on consumers and structural challenges to the stability of whole national economies.

The oil embargo was lifted in March 1974, but oil prices remained high, and the effects of the energy crisis lingered throughout the decade. In addition to price controls and gasoline rationing, a national speed limit was imposed and daylight saving time was adopted year-round for the period of 1974-75.

The 1973 oil crisis began in October 1973 when the members of the Organization of Arab Petroleum Exporting Countries proclaimed an oil embargo. The embargo was targeted at nations perceived as supporting Israel during the Yom Kippur War.

Most energy crises have been caused by localized shortages, wars and market manipulation. Some have argued that government actions like tax hikes, nationalisation of energy companies, and regulation of the energy sector, shift supply and demand of energy away from its economic equilibrium.

In order to prevent an energy crisis, it is also crucial that we consume less energy by improving and modernising energy infrastructure such as smart grid solutions, and smart cities. It is also important that we replace old devices by energy efficient solutions, such as replacing traditional light bulbs by LEDs.

According to the National Bureau of Economic Research, the recession in the United States lasted from November 1973 to March 1975. Although the economy was expanding from 1975 to the first recession of the early 1980s, which began in January 1980, inflation remained extremely high for the rest of the decade.

The two major motives for conserving energy are to save on utility bills and protect the environment….Energy conservation: 10 ways to save energy

1. Adjust your day-to-day behaviors.
2. Replace your light bulbs.
3. Use smart power strips.
4. Install a programmable or smart thermostat.
5. Purchase energy efficient appliances.

The energy problem that receives most attention is the link between energy access and greenhouse gas emissions.

Access to energy resources, or lack thereof, affects human health, access to education, socioeconomic status, gender equality, global partnerships, and the environment. 7.6 Some populations are more vulnerable to impacts of energy choices than others.

Why would we apply the precautionary principle to switching to a hydrogen economy? There are concerns that hydrogen gas could deplete the ozone layer. Of the following new renewable energy sources, which is the least developed (with the shortest period of experimentation and research)?

Fuel cells cannot yet compete economically with more traditional energy technologies, though rapid technical advances are being made. Although hydrogen is the most abundant element in the universe, it is difficult to store and distribute.

So, for industrial vehicles, hydrogen seems like a viable option, despite the inefficiency. It’s likely that FCV energy supply-chain efficiency will be improved over time and more renewable energy sources used in hydrogen production.

The biggest reason why hydrogen-combustion engines are no good? They create nitrogen oxide, which isn’t good for people or the environment. Even though carbon isn’t part of the hydrogen combustion process, NOx isn’t a compromise as automakers look to zero-emission vehicles.

You won’t even go 100 miles on current tech hydrogen tanks that are still safe to carry around in a car. Fuel cells wear out crazy fast and are hard to regenerate. Hydrogen as a fuel is incredibly hard to make and distribute with acceptably low losses.

The sceptics’ first argument against hydrogen vehicles is that they’re less efficient than EVs are. Because hydrogen doesn’t occur naturally, it has to be extracted, then compressed in fuel tanks. “Lithium-ion battery production [for electric vehicles] is very energy-intensive.

However, as hydrogen cars densely pack their energy storage, they’re usually able to achieve longer distances. While most fully electric vehicles can travel between 100-200 miles on a single charge, hydrogen ones can get to 300 miles, according to AutomotiveTechnologies.

According to OSHA, “Hydrogen used in the fuel cells is a very flammable gas and can cause fires and explosions if it is not handled properly.

The two prime dangers from fuel cell and hydrogen-powered vehicles are the danger of electrical shock and the flammability of the fuel. Fuel cells power vehicles by electro-chemically combining hydrogen gas (H2) and oxygen (O2) from the surrounding air into water (H20) and electrical energy.

In the event of a hydrogen leak, the gas simply dissipates harmlessly. Moreover, the tanks that contain H2 are thick walled and carefully designed to prevent leaking, even after a substantial crash. For example, should the tanks ever be punctured, the device allows for a managed venting of the gas.

The key challenges include: Weight and Volume. The weight and volume of hydrogen storage systems are presently too high, resulting in inadequate vehicle range compared to conventional petroleum fueled vehicles.

There are two types of hydrogen engines. Say you have a petrol vehicle and convert it to run on hydrogen, your vehicle will still be able to run on petrol. This means you will be able to fill up your vehicle with hydrogen and when your vehicle runs out of hydrogen, you just swap back to petrol fuel.

This means that for complete combustion, 34 pounds of air are required for every pound of hydrogen. This is much higher than the 14.7:1 A/F ratio re- quired for gasoline. Since hydrogen is a gaseous fuel at ambient conditions it displaces more of the combustion chamber than a liquid fuel.

Hydrogen can either be burned in a jet engine, or other kind of internal combustion engine, or can be used to power a fuel cell to generate electricity to power a propeller.
