India Hydropower Output Records Steepest Fall In Nearly Four Decades (reuters.com) 69

Posted by BeauHD from the supply-and-demand dept.
An anonymous reader quotes a report from Reuters: India's hydroelectricity output fell at the steepest pace in at least 38 years during the year ended March 31, a Reuters analysis of government data showed, as erratic rainfall forced further dependence on coal-fired power amid higher demand. The 16.3% drop in generation from the country's biggest clean energy source coincided with the share of renewables in power generation sliding for the first time since Prime Minister Narendra Modi made commitments to boost solar and wind capacity at the United Nations climate talks at Paris in 2015.

Renewables accounted for 11.7% of India's power output in the year that ended in March, down from 11.8% a year earlier, a Reuters analysis of daily load despatch data from the federal grid regulator Grid-India showed. India is the world's third-largest greenhouse gas emitter, and the government often points to lower per-capita emissions compared to developed nations to defend rising coal use. A five-year low in reservoir levels means hydro output will likely remain low during the hottest months of April-June, experts say, potentially boosting dependence on coal during a period of high demand before the monsoon starts in June. [...]

Globally, hydropower output fell for only the fourth time since 2000 due to lower rainfall and warmer temperature brought about by the El Nino weather pattern, according to energy think tank Ember. Hydro output in India, the sixth-biggest hydropower producer, fell nearly seven times faster than the global average, Ember data showed.

      Nuclear is a stop gap, until renewables pick up, but is not a solution. High maintenance costs, high constructions costs, disposal of spent fuel, collateral damage incase of failure, are just some of the issues with nuclear. Not to mention that the industry is monopolized by a few small players, which is the same problem as with fossil fuels

        You have this backwards. Nuclear can't be a stopgap because it's simply not possible to build in a reasonable timeframe in which it were effective. Nuclear is a *long term* solution, but one that has an incredibly high cost. Gas is a stopgap. Solar and Wind are intermittent, pumped hydro takes forever to build, battery storage lacks manufacturing capacity.

        One interesting other one is ammonia cracking. Building out excess green energy, using the excess to generate hydrogen and storing it as ammonia in a tank to be cracked or even fed directly into turbines to provide power while the sun doesn't shine. But honestly the complexity alone here is holding it back, plus the technology isn't proven so it suffers the same problem as nuclear: timing.

          Gas is looking to be even worse then coal for global warming if you consider the greenhouse effects of leaked methane from gas plants. There was a debate here on /. a few days back and I was schooled by people on how methane is worse than CO2. So if we consider that, its better to keep burning coal than setup natural gas plants.

          Nuclear can be built cheaply and safely. You just need to get out of paranoia mode. You build small pebble bed reactors . You dont try to reprocess or refuel. You treat them like batteries. Have a few spread across a large city with local grids. When you are done, dump them in the Mariana trench and replace with a new one. Make them using Thorium so the Uranium they produce is too poisoned to use to build nukes. Thorium is lot more abundant than Uranium.

          If you are really serious about fighting climate change you need to make sacrifices somewhere else so the deep sea makes the sacrifice

          Regarding Ammonia many companies are working on NH3 based FCEVs. These will have smaller batteries than BEVs requiring less mining, similar refueling speed to gas vehicles and an existing infrastructure for transporting NH3 as well as more efficient than simply burning the NH3 in a combustion engine. NH3 is a good transition fuel as we can make it right now using natural gas but can make it in the future using electricity.

              The whole point of using new "non-established" methods is that the existing methods have failed economically. All of the existing nuclear plants have been built at scales where a single meltdown can take out an entire region so they are overengineered.

When they are small enough that a single meltdown can take out a neighborhood not a city, the amount of safety measures go way down reducing cost. We dont bui

        Renewables will NEVER be able to supply the constant and sheer amount of power that nuclear can.

        Modern reactor designs don't leave much waste. Much less than alternative energy. Maintenance is massively less expensive than solar, wind, hydroelectric, etc.

Constant power is correct, but first renewables do not need to provide constant power, the whole grid does and second, we don't want constant power anyway; we want it when we need it. Nuclear provides that as poorly as renewables, if for the opposite reason.
