England’S Wood Shortage Leads To Increased Use Of Coal And New Technology To Pump Flooded Mines
In the 1500s, England faced a growing demand for wood.
As supplies near to the towns and cities ran out, importing from farther away grew increasingly costly.
Fears of an impending wood shortage spread throughout England and something had to be done.
This led to the solution of switching to coal as a new primary fuel source for household use.
The change was initially slow, as burning coal was thought by some to be poisonous and demonic due to its foul smell and how it was mined from the ground.
Thanks to the Scottish King James VI supplanting the throne of England in 1603, people began converting to burning Scottish coal that burned cleaner and brighter rather than English sea coal.
Before long, London skylands were dotted with chimneys as everyone adopted this cheaper form of fuel.
Unfortunately this brought new unwanted issues in air pollution which caused problems with health and well-being but not enough as people carried on using this resource until easy-to-mine sources began depleting quickly leaving flooding issues in mines that had gotten too deep in order for more resources.
To save these mines from any further destruction required more advanced technology which thankfully came just in time before all hope seemed lost.
The Invention Of The Steam Engine Revolutionized Travel And Changed Our Understanding Of The World
The increased amount of coal mined in the 1700s and 1800s required an efficient way to pump the water out of deep mines.
That’s when Thomas Newcomen developed an improved steam engine which quickly replaced Savery’s machine in mines across Britain and Europe.
Although the Newcomen Engine was effective, it lacked power.
James Watt stepped in and made a tweak to Newcomen’s design by adding a separate condenser, which produced a much more efficient steam engine.
This ushered in an affordable, more flexible form of energy that had other uses beyond powering pumps for mines; steam locomotives were used to haul heavy loads along iron rails and even eventually connected cities through railways – something unheard of before Watt’s invention!
The new access to railroad transportation meant that travel no longer depended on an individual’s or their horse’s stamina as they could now experience places previously inaccessible.
The advent of steam-powered engines truly changed the game regarding industry, transport and exploration.
The Need For Artificial Lighting Led To The Discovery Of Oil And Electricity
The development of artificial lighting was one of the driving forces in the discovery of oil and electricity.
In the early days, candles and oil lamps were unreliable sources of light, and they couldn’t provide enough illumination to light up entire cities.
William Murdoch solved this problem with his gaslight invention, which provided brighter light than any other form of public lighting before it.
But this solution was only used for public and industrial lighting, so regular people still relied on whale oil for their homes – until it became too scarce and too expensive due to overhunting.
People then had to look for something else as fuel for their lamps, which eventually led them to petroleum.
For years petroleum had been an ignored source of energy until it was discovered that it could be used to produce kerosene, a cheaper alternative to whale oil.
It wasn’t until Michael Faraday’s breakthrough discovery in 1831 that people could begin to put electricity to use as a form of artificial light.
Electricity could be generated by turning a crank or using large sources like waterfalls.
Finally, in 1882, the world’s first hydroelectric plant began generating power along the Fox River in Wisconsin – providing electricity not only for production processes but also for illuminating homes and streets.
Wars, Distribution Challenges, And Resource Depletion Drive The Adoption Of New Energy Sources
Throughout history, scarcity of resources and outside forces have played a major role when it comes to the development and adoption of new technologies.
People are often forced to look for solutions due to the depletion or limited availability of a specific resource.
Take oil for example.
In times past, no one even knew how to store or transport oil — it was transported in leaky wooden barrels stored on rafts that traversed raging rivers — making it very difficult for this technology to take off and become widely adopted.
Similarly, after Pittsburgh briefly converted from coal to natural gas in the 1880s and experienced an improvement in air quality, their supplies were depleted by 1892.
It wasn’t until 1947 that they got their supply back with the Big Inch pipeline, which had been constructed to deliver oil during World War II but was subsequently converted to supply natural gas.
The automobile provides yet another example wherein a finite supply of natural resources spurred advancements in technology.
Early cars ran on different types of engines fueled by steam, electricity, alcohol, or petroleum — each battling out against one another — until petroleum eventually won out and became the norm.
Again, fears grew about petrol supplies as early as 1920 when scientists expressed concerns over depleting US reserves which ultimately led to drilling efforts elsewhere such as Saudi Arabia — resulting in entire wars fought over control of these resources.
The Rise Of New Energy Sources Brings About Sweeping Lifestyle Changes
The changes brought about by each new energy source has a far-reaching impact that often extends to other industries.
For example, the rise of coal as an energy source in England shocked society and required lawmakers to intervene in order to regulate working conditions with the Mines Act of 1842.
And in America, when automobiles began replacing horses, it changed so much more than just the transportation sector.
Prices for crops dropped since there was less of a demand for horse feed, and many who had found profitable work providing hay and fertilizer suddenly found themselves out of business because horse manure could no longer be used as fertilizer.
Overall, this highlights that whenever there is a new energy source introduced, we can expect larger ripple effects within unexpected sectors.
An important lesson to remember is that no matter how unrelated industries might seem to one another, they still need to understand how developments and changes in one sector can influence those seemingly unrelated industries too.
Environmental Consequences Of Energy Use Are Too Often Ignored Or Neglected
The environmental impact of energy use is almost always an afterthought, and this has been a theme throughout history.
Take smog as an example: after the industrial revolution, it appeared over coal-burning cities, yet very few people recognized it as a health hazard.
Over time, this changed and air pollution was considered something to take seriously – but again it took some catastrophic events for that to happen, such as the toxic fog incident in Donora, Pennsylvania in 1948 that killed 20 people or another similar incident in London in 1952 where 3,000 died due to toxic fog caused by sulfur dioxide from coal smoke.
Invisible pollutants from cars and oil fields also played their part in contributing to air pollution – yet this detail was largely ignored and often denied by the automotive or oil industries.
Finally, with some perseverance thanks to geochemist Arie Haagen-Smit’s research proving both the cause of air pollution and its damaging effects, President Richard Nixon created the Environmental Protection Agency in 1970 to properly tackle this problem.
It’s thus become clear that taking environmental concerns into consideration when using energy is important – and unfortunately a lesson we can’t seem to learn quickly enough without drastic incidents occurring first.
The Key To Addressing Global Energy Demands In The 21St Century Is A Holistic Approach Combining Renewable And Nuclear Sources
As the global population steadily increases and moves towards the estimated 10 billion people by 2100, there is a need for reliable, affordable energy in order to provide sustenance.
Future energy needs must supply reliable, affordable energy to a growing world population in order to ensure that everyone has access to the necessary resources they require.
Wind and solar power have both been used as renewable sources of energy since the late 1800s and 1950s, respectively.
While wind turbines only have a 34.7% capacity factor and solar cells boast 27.2%, much research has gone into improving these numbers over time.
However, even with these advancements there is still the possibility that either or both these technologies may not be able to sustain the needs of a rapidly increasing population.
In contrast, nuclear power plants can operate at an impressive 92.1% efficiency which makes them an incredibly cost-effective option when compared with other traditional forms of energy (e.g., coal or natural gas).
Coupled with its high capacity factor, this makes it a viable option for future energy needs to meet demand when other sources are not available or unreliable due to weather conditions, etc..
We Must Act Now To Ensure Our Energy Needs Are Met For Centuries To Come
Climate change is driving the need for a mix of energy sources that reduce carbon dioxide emissions.
Renewable, nuclear and future sources are all being considered in order to decrease dependence on fossil fuels and combat the effects of climate change.
This means diversifying our energy sources away from just fossil fuels and investing in renewable, nuclear and other alternatives which don’t contribute to climate change or make use of finite resources.
Renewable energy sources such as wind, solar, geothermal and hydropower produce minimal or almost zero carbon dioxide emissions.
Nuclear energy is another source that produces no direct emissions but does have questions about its waste management and waste products.
Future technologies such us fusion could also be explored; these are still in their early stages but offer the promise of generating electricity with low greenhouse gases emission.
The switch to this combination of energy sources requires patience as it takes time to build out the necessary infrastructure, refine technology and get people comfortable with the new ways.
Nevertheless, even small steps towards decarbonisation can go a long way in helping reduce emissions and leading us into a better future for our planet.
