Wind, solar, biomass and hydroelectric is having an impact on your life and could have an even bigger impact in the future. Renewable energy, in the most basic terms, is precisely what it sounds like. It’s power that comes from sources that regenerate, unlike fossil fuels, which only exist in a limited amount.
Urban waste management has emerged as a big challenge for the government and local bodies in Saudi Arabia. The country generates more than 15 million tons of municipal solid waste each year with per capita waste production estimated to be 2 kg per day, among the highest worldwide. Municipal waste production in three largest cities…
Trinidad and Tobago is said to produce 14.4 kilograms per capita per day of municipal solid waste (MSW). The amount of MSW produced by Trinidad and Tobago is 150 per cent more than second place Kuwait.
Joel Julien (Trinidad Express) writes that, according to a report by Worldatlas—“Countries Generating The Most Trash Per Capita”—Trinidad and Tobago generates the most trash per capita in the world. Besides Trinidad and Tobago, the Bahamas, St. Lucia, Barbados, Guyana, St. Kitts and Nevis, and Antigua were among the top ten. Here are excerpts:
[. . .] Sadly, Trinidad and Tobago came out in first place. According to Worldatlas “a lack of recycling facilities” contributed to Trinidad and Topbago’s “dire waste management issues”. We were also slammed for our “pervasiveness of littering”.
Trinidad and Tobago is said to produce 14.4 kilograms per capita per day of municipal solid waste (MSW). The amount of MSW produced by Trinidad and Tobago is 150 per cent more than second place Kuwait. Kuwait is said to produce 5.72 kilograms per capita per day of MSW. The worldwide average for MSW production is 1.2kg.

The greatest environmental downside towards utilizing lead for lead acid batteries is the waste produced in processing lead and the damage created in the mismanagement of lead that is being recycled (as lead still is a toxic material to deal with). Our greatest priority moving forward with lead should be to utilize research efforts into producing cleaner processes for handling lead, and researching stricter procedures for the recycling of lead.
It’s no stretch to say that electricity powers our world. A wide variety of appliances serve critical purposes in ensuring the health, efficiency, and security of the human race. From automobiles to medical appliances, it is no stretch to claim that batteries serve a critical role in society to power crucial portable appliances.
As discussed in my previous blog post, Lead Acid batteries firmly stand as the industry standard to power our heaviest appliances, mainly due in part to it’s economic advantage over alternatives on the market. However, there do exist alternatives. From older batteries, such as Nickel Cadmium, to more modern batteries, such as Lithium-ion, Lead Acid batteries fall short in smaller devices due to the energy and weight efficiency exhibited by the newer Lithium Ion battery.
