Climate Change and Technical Work
Climate change affects humans and natural environments today and particularly in the future. Housing, transport, energy generation and building construction are closely linked to climate change and technical work skills. Therefore, technical work plays an important role in understanding climate change in-depth and building a climate-friendly world.
How big is your Carbon Footprint?
Food, travel and housing are the largest components of an individual’s carbon footprint. Lifestyle choices make a big impact on personal carbon emissions. The text about home economics discusses food carbon emissions, whereas this text concentrates on discharge from housing and transport.
Material Use has an Impact on Climate
Our consumption rates of natural resources, such as wood, oil and metal, are excessive, and renewable energy sources are struggling to keep up with high demand. It would take 1.3 Earths to sustain our current consumption level. Saving natural sources has a two-tiered connection to climate change: use and processing of natural resources amplify climate change, and climate change in turn has an impact on the amount, quality and distribution of natural resources by changing the growth rate of trees and the amount of fresh water.
Energy Generation can amplify or slow down Climate Change
Before the Industrial era, wood fuel, water wheels and windmills generated most of the energy. Agriculture and transportation used horsepower. World energy use increased more than ten times in the 20th century from 911 million tonnes of oil to 9645 million tonnes when the world’s population went up from 1 billion to 6 billion. Today coal, oil and natural gas are the most important non-renewable energy sources. Compared to these, the share of nuclear energy usage is relatively small. Renewable energy technologies are constantly under development around the world and lately, wind and solar power, geothermal energy, and hydroelectricity technologies have improved by leaps and bounds.
