Only 2.5–2.75% is fresh water, including 1.75–2% frozen in glaciers, ice and snow, 0.5–0.75% as fresh groundwater and soil moisture, and less than 0.01% of it as surface water in lakes, swamps and rivers. Freshwater lakes contain about 87% of this fresh surface water, including 29% in the African Great Lakes, 22% in Lake Baikal in Russia ...
The water supply of Paris was privatized in 1985 when a conservative mayor awarded two lease contracts, each covering one half of the city. In 2010, a socialist mayor remunicipalized the water system of the French capital. The water supply of Barcelona has been managed by a private company, Aguas de Barcelona, since 1867.
Solar. v. t. e. Historically, the main applications of solar energy technologies in Canada have been non-electric active solar system applications for space heating, water heating and drying crops and lumber. In 2001, there were more than 12,000 residential solar water heating systems and 300 commercial/ industrial solar hot water systems in use.
Peak water is a concept that underlines the growing constraints on the availability, quality, and use of freshwater resources. Peak water was defined in 2010 by Peter Gleick and Meena Palaniappan. [1] They distinguish between peak renewable, peak non-renewable, and peak ecological water to demonstrate the fact that although there is a vast ...
The second-largest single source of power (15% of the total) is nuclear power, with several plants in Ontario generating more than half of that province's electricity, and one generator in New Brunswick. This makes Canada the world's sixth-largest producer of electricity generated by nuclear power, producing 95 TWh in 2017. [5]
The tax is a 5% tax imposed on the supply of goods and services that are purchased in Canada, except certain items that are either "exempt" or "zero-rated": For tax-free — i.e., "zero-rated" — sales, GST is charged by suppliers at a rate of 0% so effectively there is no GST collected.

Cost of electricity by source. Different methods of electricity generation can incur a variety of different costs, which can be divided into three general categories: 1) wholesale costs, or all costs paid by utilities associated with acquiring and distributing electricity to consumers, 2) retail costs paid by consumers, and 3) external costs ...
The total volume of water on Earth is estimated at 1.386 billion km 3 (333 million cubic miles), with 97.5% being salt water and 2.5% being freshwater. Of the freshwater, only 0.3% is in liquid form on the surface. [ 2][ 3][ 4] Because the oceans that cover roughly 70.8% of the area of Earth reflect blue light, Earth appears blue from space ...
